As of today, I am unable to scroll with my mouse in google sheets. The scroll bar on the right disappears and I'm taken to the bottom of the spreadsheet and can't scroll back up. I have to use CTRL+Home and then the arrow keys to go down the rows. This appears to be only on Firefox. I tried a different browser and it worked fine.

I use Mozilla Firefox for work. Part of my work requires I use the GlobalProtect VPN client. When I log on to the VPN, everything appears to be fine. The problem arises when I log out of the VPN client, such as needing to switch to a different VPN.

When I log out of the VPN client, Mozilla slows down massively. I get the following errors when trying to access websites.

PR_END_OF_FILE Timeout

I thought it was a DNS issue, but the change I made previously did not prove to be a reliable fix, and I do not actually know the root cause of what is happening. Firefox returns to normal ONLY after a full computer restart. At this point I am considering switching browsers as, despite Firefox's functionality, it is starting to interfere with my work.

I have used other VPNs, such as Fortigate VPN, and not encountered anything like this.

Any advice or guidance would be appreciated.

Hi, i have problem with uninstalling uBlock Origin i cant remove them from extension tab. I tried refreshing firefox, reinstalling, opening firefox with troubleshoot mode and still nothing i dont know why is so difficult.Even when i reinstalling firefox this addon onstalling by itself even when im not logged in.Please help me. Thanks

This issue is happening with every newly installed add-on, but not with add-ons installed on or before Aug 3, 2024. The add-ons are installed via addons.mozilla.org. To rule out the possibility that it's happening only with specific add-ons, I also installed one of the random recommendations on that page, Augmented Steam which has 54,248 users, and it happens with that one as well.

I'll click Enable, but the prompt appears every time I restart Firefox.

What I've tried (with a restart after each attempt):

• Clear the startup cache
• Delete extensions.json
• Delete compatibility.ini
• Via about:config deleted extensions.databaseSchema and extensions.getAddons.databaseSchema
• Excluded Add-ons from syncing

I've noticed the following in extensions.json for each of the recent add-ons after restart:

• syncGUID changes to presumably random new value
• active changes from true to false
• userDisabled changes from false to true
• seen changes from true to false

Hi

OK so I was having some issues with firefox where I had to reinstall it and this did in fact resolve the issues I was having.

Problem I have is this though when I reinstalled it I first backed up my chrome folder which had all my custom CSS to move the tabs to the bottom of the header area and when I then reinstalled FF I then copied the folder back into my profile folder using the More Info under the help menu to make sure I was in fact in the right profile folder.

Problem is the code isn't moving the tabs and I seem to remember some issues with this the last time we had to fix FF that something had changed with the Chrome folders and such.

So what do I need to do to get my tabs back on the bottom again as I hate them up top!

Version: 128.0.3

Thanks!

Twitch, Youtube Live, Netflix, Kick... it seems any live streaming platform cannot play. I am running Linux Mint 21.3, Kernel 5.15.0. They work on a different browsers, they all also work on Firefox my laptop, which is also on the same OS and Kernel.

I have tried everything: installed ffmpeg, installed unrestricted ubuntu codecs, refreshed firefox (twice), uninstalled/reinstalled firefox, ive tried without extensions, yet nothing.

Cant for the life of me figure it out, im not sure if its my PC or Firefox on this machine.

Can't pinpoint the date, but a while back Youtube won't play videos anymore. It just shows a black screen in the player. Not even the player UI (pause button, volume, settings menu) shows. Just a black portion of the screen. Now when I went in to get a screenshot, it doesn't even show the black box.

I'm looking for the best way to integrate idm integration module in Firefox to get all Internet download manager features.

IDMIntegrationModule.com guide provides 2 methods to do that which one should I use:

1. IDM CC for Firefox 2. IDM Integration Module Firefox Add-Ons

Thanks.

Hello!

I found the new "Close Duplicate Tabs" and would like to suggest the following, for improvement for power users.

1) It should be possible to configure an option for what should happen with the duplicate tabs. For example: it should be possible to move all the Duplicate Tabs to a new Window - so I can view all these tabs and compare them (and close them if I want that) Reason: I use a web interface to a database for documentation and sometimes I have more than one tab open with the same article - but the software behind it doesn't notice, it just stores what comes out and so it would happen that an article is accidentally overwritten.

2) According to what criteria are the duplicate tabs compared - can you set options here?

Best wishes! hannes

Hello. Recently I've noticed video quality has been reduced on amazon prime video. I get a message saying my hardware doesn't meet HDCP requirements.

I've already tried playing the same video on edge, and the quality selector was fine there, full HD video.

Thank you in advance

I'd like to add Firefox to Adobe Dreamweaver for site design viewing. When searching Windows for Firefox.exe I don't see it in Program Files or Program Files (x86). Firefox is installed and used daily. Can someone tell me where it's located in Windows 10?

When I try to play a video on Firefox desktop, it takes it a long time to load. Once it has loaded, whenever I pause it for more than a few seconds, or if I try to skip around the video (either by clicking around in the loaded section of the progress bar or using +/- seconds buttons), the video begins buffering again before the video resumes. This makes it extremely difficult and frustrating to watch anything that requires me to pause, rewind, or fast forward. I've noticed this issue affect multiple video viewing sites, such as YouTube, Vimeo, and Netflix. My roommate also uses Firefox, but doesn't have this issue, so I know it's not a problem with my internet. I thought it might be a problem with my computer, but I tried to replicate the issue in Chrome and everything worked fine there. The issue has persisted almost a week. I have:

• Rebooted my computer several times
• Deleted my history/cache
• Disabled my extensions
• Turned off Java scripts in firefox (this disabled my ability to load sites like YouTube completely, so I turned it back on)
• Updated my computer
• Updated my graphics drivers
• Refreshed firefox
• Uninstalled and reinstalled firefox (and rebooted my computer)
• Uninstalled and reinstalled firefox AND deleted all the data it stored on my computer (and rebooted my computer)

I am currently using version 123.0.1 of Firefox. My OS is Windows 10 22H2.

When I am browsing in either regular mode or safe mode, the scroll buttons for next or previous slide do not appear on the MSN web page. However, if I open a private browsing tab from either regular or safe mode, the scroll buttons appear and are functional. I am running Firefox version 129.0.2 (64 bit) on Windows 11 Home version 23H2. I have refreshed Firefox and also uninstalled and reinstalled Firefox. I have also toggled "always show scrollbars" on in Windows settings. No change. These scroll buttons function in other browsers (Edge, Chrome), but I prefer Firefox. Where do I go from here?

Edit bookmark box won't scroll or show me all my folders/subfolders: When are you going to fix this problem: https://support.mozilla.org/en-US/questions/968861

This used to work fine. I don't want to mess with userChrome.css to get it to work. It should just work like it used to.

Thanks very much...

Similar to the issue described in this thread (https://support.mozilla.org/bm/questions/1240674), I am unable to open Firefox - it simply refuses to open. I've tried multiple times, the option key, and re-installing. Nothing seems to work, which suggests something about my user settings is the issue, but a) I am not keen on deleting this if possible and b) I won't delete my user settings unless that is necessary. Like the attached thread, I am happy to attach crash reports, but without the ability to even open Firefox properly it's not obvious how I do this - force-quitting it just sends a report to Apple.

Any help much appreciated - I'd quite like Firefox working again.

My laptop is a MacBook Pro 13 2020 (Intel) running macOS Monterey (12.7.4). I installed the version of Firefox available for download as of writing (v127.0 based on Finder).

So I wanted to read PDFs trough firefox with a dark theme, looked up how to do so online, and people say to change the "about:config" option "pdfjs.viewerCssTheme" to "2" instead of "0", I did that, tried opening a PDF, nothing happend, it was still black text on white backgrounds. Tried closing firefox, reopened the pdf, nothing happened, still white backgrounds. Tried to check if it might have to do with that specific pdf file's config, created my own PDF file from a word document, tried to open it, still white backgrounds. Tried disabling extensions, (which I use four of, UBlock Origin, SponsporBlock, Return Youtube Dislike and Translate this page), didn't work. Tried enabling the option on my laptop, didn't work. Tried a bunch of other stuff and it still won't work. My Firefox version is 109 and I'm using Windows 10 I also don't want to use the console/file edit thing with grayscale(1) invertcolor(1) or whatever it was since it also reverses the colors of images instead of just the backgrounda nd text color.

On several site there's a greyed out box top right, which disables anything it covers, can't be got rid of, and makes using Firefox for these sites impossible. Help, please?? Thank you! (I'm having to use Chrome...)
