I've installed firefox with pacman on Linux, and I installed arkenfox. It did not work, I tried other user.js', none worked. I've also tried wiping my entire firefox root folder, then using arkenfox, but did not work.

Firefox should definitely add a dedicated option in the toolbar to make switching between profiles easier. Currently, the only way to do this is through the "about:profiles" tab, which is much less convenient than the profile switching options in other browsers

The Adobe Acrobat Add-On Extension for Firefox was missing so I attempted to add it from Adobe Acrobat Pro 2017. I have had to do this manually by installing from the adobe_acrobat-1.0-windows.xpi file. This usually has worked. When i tried to add it this time is said the add-on file was corrupt.

I tried uninstalling and redownlading AdobeAcrobatPro 2017 thinking this would add an uncorrupted file and got the same the same message. Unfortunately, because I had used the Adobe license key too many times for Acrobat 2017 on my computer I had to upgrade to Adobe Acrobat Pro 2020. i had hoped this would solve the problem. But no, I get the same message corrupt file message even with a new copy of the Acrobat Pro 2020.

What is going on? Can anyone help with this?

Hi, I want to use dark background color theme in the Mozilla Firefox PDF viewer, read here https://support.mozilla.org/en-US/questions/1434510 but cannot find "userContent.css". My question is where can I find this file on a Windows 7 or Windows 10 installation?

Seemingly straightforward searches through the options like:

• "Reset firefox"
• "Clear cookies"
• "Empty cache"

None of these things pull up any results when searching the settings... Why?

I have gone to sites that already have my stored password. The saved password is not populating. I deleted the password. When I go back to the same site, it did not ask to save my password even though the option is selected is settings. This started after the recent update.

As I said in the title, the spellchecker add-on I use, LanguageTool, does not work on this site. I am not fine with that. What's the best way to get it working here? Any answers that amount to "you don't" are not acceptable.

How can I change my email address in Thunderbird? My current address (very old sympatico server) is defective and I cannot respond to mail I receive. I want to create a different email address and delete the old.

Thank you, Walter Vieira Ottawa, ON Canada

Every time I shut down Windows and start it again, Firefox looses all custom configuration and does not navigate on any site. Other browsers do it: Google Chrome, Microsoft Edge.

I have to go to Menu | Help | Technical Information and clear all of them AND I have to redo all my personalized configuration like: options, buttons, bars, tools and tabs, which I get from my backup (I use the extension: "Simple Tab Groups").

How to fix it? I use Firefox for decades and I have never had this issue.

Thank anyone for any enlightenment. Ivens

Hello guys !!

I wanted to disable the prefetching/preloaad pages and I found some entries on about:config that I had to change. Some of those are here on the official support site and some not, I found them on another forum.

Here's the list: network.prefetch-next (false)

network.dns.disablePrefetch (false)

network.dns.disablePrefetch.FromHTTPS (false)

network.http.speculative-parallel-limit (0)

browser.urlbar.speculativeConnect.enabled (false)

So, my questions are: 1. All these expect one "browser.urlbar.speculativeConnect.enabled" are available on android (nightly). Is there and i can't find it or it's indeed not available ??

2. Is the "network.http.speculative-parallel-limit" works only for http or it works and for https as well ?? Is there some setting to geti it to work for https if it doesn't ??

3. Is true that the "network.dns.disablePrefetch" and/or "network.dns.disablePrefetch.FromHTTPS" doesn't work (if i disable it) if i have turned on the dns over https ??

4. Are there other settings that I need to configurate or I'm good with these ??

Thanks in advance !!

How do I either stop videos from autoplaying or auto repeating? Either one would be a blessing but I've searched and cannot find an effective way to do it. Blocking in Firefox is not effective. Mostly it seems in facebook, but I believe it repeats all the time on all sites.

Try as hard as I may from all the Help screens, I cannt find a solution to how to permanently pin the Bookmark Toolbar to the side of the screen in my version of Firefox which is 129.0.2 in Windows 11. The option to pin the toolbar where the user wants it to appear seems to have vanished. Am I correct?

The only options I can find in Firefox now are Show Toolbar and it will only appear across the top of the screen (unless I Ctrl+B); Show in new tab or Hide.

Ctrl+B will bring up the tool bar, say to the left, but when Firefox is closed and re-opened there is the need to Ctrl+B again to redisplay the toolbar. My experience of Windows 10 was that everytime I opened Firefox my side bar for Bookmarks automatically appeared because I had always been able to pin it there.

Please help to restore the function, if it hasn't been removed through updates.

Thank you.

My thunderbird setttings is not being saved. My email account is added as a pop account and supposed to be using normal password instead of oauth2. Every time I change it to normal password and close thunderbird, it just revert back to oauth2. What I did is I tried to remove the account and re-add it as an imap so that it will be able to use oauth2 since I am unable to change that settings,and it just keeps reverting. After adding the account as imap. I tested it, its working, I was able to send and receive and its using oauth2. After I close thunderbird and reopen it, the account reverted back to pop. I don’t know what to do, it seems like I’m unable to make some changes on the settings in thunderbird. Need help.

    Also we are unable to disable that option for the flash screen every time I open thunderbird.

Please respond to Owen Rice and lexusa@verizon.net

Hello,

I am reaching out to gain information on ADMX GPO policies. We are retiring Policy Pak which used to add all the policies and secure Firefox for Enterprise. What we noticed is that Policy Pak used the app set to apply these policies and we are noticing that native GPO's for the most part to match the Policy Pak policies is not as accurate for GPO's My ask here is there any Most Viable Product suggestions to apply Native GPO's for securing Firefox.
