Mozilla have now implemented a default zoom setting, although it's only available through about:config.
You can change the pdfjs.defaultZoomValue in about:config to change the default zoom.
Set it to a number for a number (no percent sign) for a given default percent zoom.
Other possible values are page-width, page-height, page-fit and auto.
With some research (see at end for 'references'), I've come up with this (kind of) simple solution:
CLOSE FIREFOX FIRST
This requires you to edit the SQLite Database (a self-contained SQL database; see Wikipedia article) of Mozilla Firefox by making a query to find all records that satisfy the condition (in your case - viewed less than 5 ...
In case anyone stumbles upon this, it's actually really simple to setup Firefox profiles to group into separate taskbar pins like the Chrome profile manager works.
I like to have a separate "personal" and "work" Firefox profile with separate shortcuts pinned side by side:
• Launch Firefox and go to about:config.
• Add New > Boolean > "taskbar.grouping....
Firstly, note that there's good reason a Firefox Refresh removes your extensions and preferences - these are usually the most likely cause of problems like slowness and bugs encountered in Firefox.
This means that Refreshing Firefox and immediately restoring everything from your old, affected user profile may leave you with a refreshed profile that ...
Using FF version 68.0.2, still no good built-in way to see the profile for the current browser session.
The best way I've found is to make an image with the text of the profile name and add about 150px of right padding. Then go into Add-ons, Themes, and at the bottom is a link to "Build your own theme with Firefox Color" (this takes you to https://color....
Do WebExtensions ever store their prefs within prefs.js?
Not if they are written according to the guidelines.
Each extension has its own storage area, which can be split into different types of storage.
WebExtensions should be using use the storage API to store the settings:
Enables extensions to store and retrieve data, and listen for changes

Firefox can't share profiles between separate installs since v67.
The two profiles, .default and .default-release, are used by installs from different update channels - like release, beta, nightly, developer-edition etc. So for a non-tech user, .default-release is the ...
I would to ask for additional info using the comment, but I can not post comments on StackExchange Network yet. Because of being a newbie and not having enough reputation points.
I currently run Linux, but I met such behaviour in the past, no matter of operating system used.
How do you start Firefox instances? Do you use original shortcuts in Start menu / ...
After some more searches, I solved it myself using the following commands:
for /f "tokens=*" %%a in ('"dir /b "%parentfolder%"|findstr ".*\.ABC""') do set folder=%%a
For deleting the contents, I used:
RMDIR "%APPDATA%\Mozilla\Firefox\Profiles\%folder%" /s /q
How do I get more detail? That directory is empty.
Normally the sync log only shows errors.
See below for instructions on enabling sync log on success.
about:sync-log provides a list with log files and shows the location
where they are stored in the Firefox profile on the hard disc.
By default it shows only errors though. Depending on how long ...
According to the Mozilla article
Browser storage limits and eviction criteria:
<profile>/storage/temporary — temporary data storage repository
<profile>/storage/default — default data storage repository
The folder storage/default is where applications and webpages store their data,
so losing it will mean that everything would need to be re-...
This is a very long answer, as I have documented all my research below. If you don't care about that, what I found was that this is a legitimate Firefox pop-up and what it is asking for is the password to open a certificate chain called My Computer (PIN Required). This appears to be installed by Symantec via the Symantec PKI Client.
If you have this ...
There are two excellent extensions that would allow you to do that:
Here is a quote from its FAQ
Can FEBE backup/restore my extensions settings?
In a word ... yes. But there is a big caveat (user beware) that comes with it. FEBE will backup your preferences (a file called "prefs.js" that contains your extension settings) but it backs up ...
No, when it comes down to it, any file can be opened with Notepad, and examined in UTF-8 format, the raw data in the file.
Contain in this is a header, and the actual raw data of the file.
The header would be the place if any that this information would exist, but, it does not. It is a 32 byte chunk that contains basic information about what the file is, ...
This should answer your questions about running multiple profiles, I do it all the time. Even shows info on having one be a "default" profile so external links (like double-clicks or from other apps) will open in that default profile only.
It's short so I'll ...
The problem was that I had a file ~/.local/share/applications/firefox.desktop containing the following line:
Exec=firefox -P -no-remote %u
That was useful to start firefox from the desktop launcher. However, that's used to control how other applications launch firefox also. Changing the line to this fixed the problem:
To continue ...
You can bypass the profile manager entirely:
@echo off & setlocal
if exist "%profile%" rd/s/q "%profile%"
start firefox -profile "%profile%"
(As I'm not on Windows right now, I'm not sure if the start is even necessary)
Note, however, that Windows 7 already has several scripting runtimes other than cmd.exe – ...
It should close automatically. If it does not, try this:
start "" "C:\Program Files (x86)\Mozilla Firefox\firefox.exe" -CreateProfile test && start "" "C:\Program Files (x86)\Mozilla Firefox\firefox.exe" -profilemanager
Run firefox with the -P option (-p or -ProfileManager would also work) to start it with the profile manager. Use that to create a new profile and make it the default. On a Mac you'd run
You would need to create another Firefox profile as follows:
Press + R
Type firefox.exe -p and press Enter to open the Firefox Profile Manager
Click on the Create Profile... button. In the subsequent window, choose a unique name for your alternate Firefox profile.
Click the Finish button
After that, you have a choice of methods to utilize:
When using Nightly you have accepted the risk of using an unstable version.
Problems such as this one are temporary bugs that are found by volunteers
like yourself and are usually quickly fixed by the developers.
If when participate in the beta-testing of Nightly (actually alpha-version),
you need to communicate problems to the developers, you should do ...
firefox --profile <profile-name> <html-file>
You could add a custom option to your file manager to open it with the given command.
I don't know if nautilus could do this natively therefore I will give an example with .desktop files.
Create an entry ~/.local/share/applications/firefox-second-profile.desktop or you could ...
It appears that Firefox portable only has one profile. Though you can copy the profile folder in FirefoxPortable\data\profile to FirefoxPortable\data\profile2 for example. You can then make changes to this file FirefoxPortable\Other\Source\FirefoxPortable.ini as such:
Firefox Multiple Profiles: the easy way describes a way of ...
Use from console the command line option:
firefox --profilemanager &
This will open firefox in the Profile Manager mode and can be done multiple times, thanks to the ampersand (&) at the end. This will start Firefox and return to the prompt again (though some debug info may show, just hit enter again, arrow key up, and enter key again :)
start thunderbird with the --no-remote option. From man thunderbird:
Don't connect to a running Thunderbird instance. Don't accept or send remote commands. This option can be necessary in conjunction to several of the options above, that won't have any effect when an Thunderbird instance is running unless -no-remote is used at the ...
