You don't need an addon to do it - hit shift-f2 for the console then type in screenshot /path/to/file --fullpage (or just a filename, it'll save it to downloads as a png by default). It even gives you a little popup image of the screenshot taken. On Windows, backslashes must be backslash-escaped, so to save into c:\webpages\today\softwarerecs.png you need ...
Xmarks syncs bookmarks, history and open tabs cross browser.
I believe the open tabs sync is a premium feature but the rest is free. You can see more features here but it definitely has features you're after. I don't use this any more as I only tend to use Chrome now but I have used it for several years (up until recently)
The URL at the top and at the bottom of each PDF page is the default setting,
but that doesn't mean it cannot be changed.
Whenever you want to print a web page as PDF, go to File -> Print -> Print to File (output format as PDF, obviously), then select the Options tab, and in the Header and Footer section you can choose what to add in the header and footer ...
As we are here to recommend software, and OP explicitly asked for a Firefox extension, let me add to ᔕᖺᘎᕊ's answer:
Using profiles as suggested by ᔕᖺᘎᕊ is a good start – but to always have to go via Firefox's profile manager is not really comfortable. To make switching between profiles easier, you might wish to take a look at the Proflist Firefox extension, ...
You can use inspect element to get the "Unique Selector", then input that into the firefox console (hit shift-f2) and type in screenshot --selector <unique_selector> --clipboard to save to clipboard or replace --clipboard with the filename to save it.
In short, you can do this in Firefox with no addons whatsoever.
Nimbus Screen Capture - editable screenshots
Has the ability to save the entire page exactly as you see it
You can save in JP(E)G, PNG and BMP (or copy to clipboard and paste into any image editor)
Works on all Firefox versions from 4.0. I think it's platform-independent. Confirmed, works on Windows and Linux
Firefox is the only dependency
First, Ghostery is made by Ghostery Inc. an ad company. I'm sure their research is respectful but it is good to know about it at least.
I would try Privacy Badger made by EFF. The way it works is that it checks the requests (mainly third party ones) made by the browser and builds a blocklist based on what it detects. The upside of this is that it changes ...
My recommendation clearly is CoLT. How it matches your requirements:
Copy on Ctrl-C: Sorry, no – that would interfere with pre-defined shortcuts. But as your second option names Context Menu: Yes, definitely.
Copies title and URL of current page: Sure. In different formats. Even by formats you define.
So here come the goodies. First, it is operated via the ...
Instead of using a separate extension designed for this, just use Firefox's built-in solution of having separate user profiles.
You can find more info on setting this up over here at Firefox's website.
Basically, to set up, open the Run dialog (Win + R) and type firefox.exe -p (p for profile). Everything else should be fairly self-explanatory, but check ...
Using the profile manager like others have suggested, while practical, seems a bit overkill and may be a bit clumsy, as you would have to wait for profiles to switch constantly. (Or you could run multiple browsers simultaneously, but this would get pretty heavy and cumbersome very quickly.)
There's an extension called Priv8, which allows you to run tabs in ...
There are several options:
Auto Tab Discard (Compatible with Firefox Quantum)
Use native tab discard method to automatically reduce memory usage of inactive tabs.
One Tab (Compatible with Firefox Quantum)
OneTab - Too many tabs? Convert tabs to a list and reduce browser memory
Dormancy (Compatible with Firefox Quantum) [Experimental]
In firefox urlbar:
type in about:config and press enter.
Then try this: type in dom.event.clipboardevents.enabled in the bar below the url bar, and set to false by double clicking on the true.
This should disable clipboard manipulation.
hmm I can't think of anything that does exactly what I think you want to do.
However I have a pretty close option; Adblock Plus.
To go over your requirements:
Open source: Yes.
No 'dial home' features: auto-updating is the norm for Firefox extensions; that can be disabled in Firefox; Adblock Plus also has filter lists that can be set to auto-...
Firefox profiles store website passwords in an easily decryptable format (Base 64, so it's more about encoding than encrypting) only if no master password was set (if a master password is set then 3DES is used by default).
FireMasterCracker can recover the master password successfully from any Firefox browser, starting with version 1.0 or more. (dictionary-...
Great question, I've never found an OSX app to do this, so I've used the following Applescript (edited to work for Firefox, instead of Safari):
tell application "Google Chrome"
set urlChrome to get URL of active tab of first window
tell application "Firefox"
open location urlChrome
Pretty simple - get current tab in Chrome's URL ...
I'd suggest using cookies-based approach, instead of browser-profile ones.
Because cookie solutions:
are faster and more convenient - switching profiles takes browser restart
need less setup - no need to replicate
more direct solution - profiles deal with cookie collections too, not using profiles unless explicitly needed has less layers of indirection
I recommend Copy Urls Expert, a good balance in terms of customization and ease of use.
I needed a Firefox extension that could copy the web address (URL) of each tab into the system clipboard. Copy Urls Expert fits my needs and it matches the OP's requirements as well, so I've decided to add it to the answers.
From the Firefox Add-ons page that I've ...
Easy Copy (website)
Allows you to copy the link and title of current tab through context menu or keyboard shortcut
You can't use Ctrl+C to copy, Easy Copy uses Ctrl+Shift+Y instead.
Unfortunately, there doesn't seem to be an option to configure custom shortcuts, but I could be wrong.
Easy Copy uses pre-configured templates
You can also add various ...
Multifox is a Firefox add-on that
allows Firefox to connect to websites using different user names. Simultaneously!
Those identities are called Identity Profiles, which can be named (e.g., "Private", "Work", and "Sockpuppet"). Cookies are shared only within a given Identity Profile (so if you have several windows open with the same Identity Profile, then ...
I use Tab Mix Plus :: Add-ons für Firefox - Mozilla Add-ons, which can do that and much more:
Context menu of Tab Mix Plus (click image for larger variant)
As you can see in the screenshot, I'm on the right-most tab, while I opened the context menu of the left-most tab. Using the highlighted menu entry, I get the URL of the latter copied to the clipboard.
I've made a userscript to do this - it adds another sort button on the answers tab:
I've tested it on Firefox and Chrome on this question.
It will take the votes and sort them in descending order without taking into account which is the accepted answer (which it seems the 'votes' tab does currently).
To use, install Greasemonkey (on Firefox) or ...
There is another add-on called Stylus which is a Stylish fork for Firefox, Chrome and Opera without analytics.
I wanted to update the answer to this question, because as of August 2017, Stylish has apparently become associated with tracking user browsing, and I'm concerned with it sending my browsing data to third parties.
It is a slightly different workflow but very similar results; I would recommend Tab Mix Plus (TMP). Specifically I would recommend you enable the bookmark tab entry on the tab context menu (addons->TMP->option or Tools->TMP Options and check the bookmark tab entry in the Menu->Tab Context Menus page (see below for screenie).
Then just right click any tab ...
I recommend you Google Cloud Print.
It allows you to print documents from anywhere, also saves a PDF version of it in your Drive (cloud). Thus, satisfying both of your needs.
You don't have to download the app or plugin, you can use it's web version here: Cloud Print.
I suggest you to use the web version because, you use Firefox, which requires some ...
You could use Stylish (FF) --- Chrome and install user styles built for darkness. I'm personally using a few 'skins' on Firefox and Pale Moon. Some sites are a bit buggy and require you to exclude sites from time to time.
I'm using Black Web and ...
