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.

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

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.

I was registering for a web page & up popped an old deleted email with password. The email was deleted in 2016. I would like that email & any sites I used it for to be deleted from my computer. Microsoft deleted the Hotmail in 2016 so of no use.

When going to the Settings tab, Firefox shows me the message "browser is managed by your organisation". However, I am not part of any organisation, since I am a private individual.

• What does this message mean?
• How can I remove this message and regain control over the Settings in MY Firefox?

Hello, I am hoping to escape the Apple + Google search world and am trying out Firefox, which I used to use many years ago.

How do I / Can I show my Safari "Favorites" on the homepage of Firefox? A simple, obvious question, but I have not found an answer in your files.

Thank you,

No answers to how to do this, even googling. The best I get is to click on the 3-vertical-dots icon next to the intended address's url field. No such icon exists, nor it to be found in "Customize Tools"

Foxfire refuses to load roboform as my start page. It keeps referring me to install the roboform extension. I don't want the extension. I want to see my roboform when Foxfire opens. Is there a work around? https://start.roboform.com/

I need to search for more than one search term in about:config. How can I do this?

Is there some kind of syntax I can use like the pipe symbol to do something like oneword|anotherword or do I have to know literally the exact thing I'm looking for before looking?

thanks in advance
