I can't figure out how to delete this extension: Adobe Acrobat. It's disabled, but I want to delete it.

My keeper add-on needs me to enable permissions for a new feature (Access Browser Activity while Navigating), but I can't find anywhere to enable that permission. In my add-on manager page in firefox it lists the Keeper extension, but gives no option to enable the needed permission. Can anyone help me out?

I downloaded and installed the new version of Firefox a few days ago, and since then it has been running increasingly slowly; sometimes it takes several moments longer than usual to connect to a website, sometimes my cursor hangs when I'm typing. If I quit Firefox and relaunch, it functions normally, but then slows down again. I'm on a Mac running System 10.14.6, and I have a Dashlane extension mounted in the browser. Once I've engaged Dashlane, Firefox seems to slow down quickly, so I am wondering if the problem is partly the way the two are interfacing, or if there are other factors.

Chrome runs normally, as does Thunderbird--only Firefox seems to be struggling right now. Can you help?

Thanks!

I have a good 1080p monitor, which I can set up in either orientation. I have a hard time finding monitors which meet my accessibility needs, so a square/squarer monitor or a 2nd monitor would be expensive.

I have tried setting it up in vertical mode, to make it easier to read pdfs and to write. And ideally, to make it easier to avoid sidebars and/or move them away above the main content where they're less likely to trigger as many @##$% migraines.

I've noticed that most websites are designed for the horizontal layout. Elements disappear off the right edge, sometims with a horizontal scrollbar to reach them, sometimes without. Is there a trick to get miost or all websites to fit?

I use about:config fixes, add-ons, and user css to try to increase font sizes, switch colors, block animation, and reduce frame rates to completely block "smooth" animation. I can't do without these, so I don't think I could adapt the mobile version to my needs.

I've noticed *many* other problems in other apps, but if I can get all these websites working in Firefox, I can probably sort out the other problems elsewhere.

For the longest time (can't pinpoint when it started) I've been having issues with Firefox on desktop (Macbook) playing videos and occasionally audio. Video playback will be functioning fine, then there seems to be a "trigger"...For ex. I have noticed this is often me trying to play a Twitter video, which won't play normally, and suddenly NO video playback of any kind (and sometimes audio) will work...Youtube, Netflix, you name it.

The only thing that "fixes" the issue (until it pops up again the next time) is quitting Firefox and starting it back up again, usually clearing my cache first for good measure. I have tried disabling all extensions and it has no effect. I have tried playing the video in a private window/incognito—no effect. If I open up Chrome and try to play the same videos I have absolutely no issues.

My Firefox says it is currently up to date, though I am running an older version iOS (Mojave). I have googled and seen many other people having this issue but haven't seen anyone chime in with a fix that actually works. Any ideas?

Hi, my shortcuts have all disappeared. I've looked on the browser.newtabpage.pinned and all of my saved websites are listed there. But when I open a new tab they're all blank and I can't seem to add any new shortcuts either. (Also I'm not good with technology so if you do have a suggestion on how I can fix this please tell me exactly where I need to type in a command or whatever because I didn't realise I could do that until just now.) All my bookmarks are still there and obviously it remembers my saved sites so? Thanks :•)

I think Firefox just updated to 106.0.1 (64-bit). Since then I am not able to play videos on certain sites that I need to for work. I get a message "This video cannot be played (error code 224003)" This happened last year and I can't figure out how I fixed it other than it is definitely Firefox.

The website that breaks is: https://travelfilmarchive.com/home.php

I've lost all my open tabs....and I can see them in history, but when I open any historical item,...it loads it over the top of the only open tab I now have...as a result I only have one tab. Its a mess what have you done?

Hi. When I am on Outlook email account, it stopped doing spell and grammer check, which usually indicates with red wave underline idit's incorrect. It was working before. I conatcted Outlook already. After testing, it works with Safari browser on computer, and Android on my mob. Only when I use Firefox, which I have been using for years. I checked Firefox settings, and it's ticked on automatic correction. I did a few times untick and tick again, turned off and on computer. But still no luck. Why??? Please help.

Back when I used Chrome, there used to be an option when you could right-click a word and get an option in the context menu to "look up". In Firefox this doesn't seem to be the case. Is there a way to enable this? For those of you who don't know what feature I'm talking about, here's Apple's write up: https://support.apple.com/guide/mac-help/look-up-words-mchl3983326c/10.14/mac/10.14

I've also included screenshots of the feature working in Chrome.

Dear community, I have used firefox for years now and I had it synced with my email adressed. Today I wanted to login with a second profile (from my work) (I did this via about:profiles, adding a new profile) and when I logged back into my private email I had to change the password since I forgot. Suddenly ALL my user data was deleted, my passwords, my bookmarks, my history. It even shows in my profile that I just opend the account with that email adress now, today, even though I had my account for years. ALL my data is lost. PLEASE help! I am desperate. Thank you sooo much <3

Whenever I change my VPN (not Mozilla VPN) status, Firefox will refuse to connect for something like 30 seconds then times out, leaving me with a blank screen. I have wait until that interval has passed before I can retry, otherwise it will repeat the freeze. This happens whenever I turn my VPN on/off or switch to a different VPN server. It happens only with Firefox. Chrome and my email client have no problems whatsoever. I think it's some kind of DNS caching problem within Firefox as the problem doesn't happen if I visit a site that I hadn't visited very recently. There's immediate response if I do that. I have DNS over HTTPS and secure DNS turned off in the settings, so it can't be those.

Anyone else have this problem? I wish there was some way to clear Firefox's DNS cache other than having to go into about:networking

Since update 106, there is a new dock icon for Firefox on MacOS tailored for Big Sur an above. I'm still using Mojave for 32bit apps, and it doesn't look as good. Can we have an option to revert back to the old dock icon?

I want to know what caused the Firefox icon to disappear from my dock and be replaced by the generic icon. Firefox seems to continue to work well. I don't want to re-install it when it seems to work. However, I want to know what caused this to happen and if there is an easy way to restore it to the unique icon. I've read about the various remedies but don't want to take the time for a re-install when everything seems to be working.

Please just tell me the cause and if there is an easy solution.

On the opening splash page (when a new window has been opened) upper-center is the large firefox icon, then below that is the search dialog box, then below that is a series of icons (for me now, there are 8 of them). How do I add icons to this? I know how to remove, but I can't see a way to add the icons I use constantly.

How do I download 68.10 ESR? Later versions break my files. Don't know why and can not get newer files. All I get is newest version, not the one I need. I can get to the older version directory. But which file do I get?????????

The Firefox file "chs_intelligence.json" appears in the main hard drive of my Macbook Pro laptop, along with more of these files with names such as "chs_intelligence.json.15q0fp" etc. What is the function of these files, and can I delete them without disrupting the functioning of the browser? I am using Firefox version 115.1.0esr (64-bit), Mac OS x 10.14. Thank you.

I would like to be able to control which OS and version is reported by my browser to sites like https://www.whatsmybrowser.org/ . I can do about:config but I don't see which setting has that info, to change it. I also see a User Agent Switcher extension, but it doesn't let you set the version of the OS. https://www.whatsmybrowser.org/ clearly shows my OS and version, so I know it's there somewhere. How do I change it?
