Firefox Community Forum

I've used FF for years. The last year, it does not function correctly on about 20% of sites. I suggest focusing on making it compatible, rather than requiring sites that are perfectly coded. I may have to drop FF soon.

Hi, In the last hour FF has stopped working completely. I made the mistake of using Ccleaner, which is probably the problem, I haven't had issues cleaning before, though I usually check the registry before deleting and don't recall seeing any entry for Mozilla (I may be wrong, though).

Firefox was working fine a couple of hours ago, but now it won't open at all, except in admin mode and then it won't open any links or tabs, not even settings. I've uninstalled FF, deleted the folder in the Programs folder, and reinstalled it from scratch, but there is no change (the one difference is that it wouldn't open in Admin after before I reinstalled it). Waterfox doesn't open either, but Thunderbird seems to work with no problems.

Thanks, Matt

When I open one tab on Firefox, my task manager shows multiple programs running along side it. I know some extra processes are needed but this seems like an unusual amount. I have included a screenshot of the tasks that appear. When I try to delete these, they reappear. I have tried various online solutions such as uninstalling and reinstalling, and checking various settings. It is affecting my computer's performance and I am not sure how to solve this. Thank you!

In Firefox, recently I am unable to download pdf documents. I get the message "download failed". If I request the same download using Chrome, I get the download immediately. But Firefox is my default browser and it's a nuisance. This only started in the past month or so.

Why does Firefox Desktop now completely crash every time I press the Ctrl and cursor keys whilst navigating through text?!!! Very frustrating and I've had to abandon using your app completely. Please fix and redeploy your app as a matter of extreme urgency!!! thanks

Recently, the Firefox browser stopped working. Specifically for me, Costco's website, and Aetna. I believe the issue could be that those websites require that the location is confirmed, but no pop is generated, thus causing the website to not work with Firefox. Please help me, as your browser is the best.

For some reason, IDM will not work in Firefox/DuckDuckGo. even though it worked a couple of weeks ago. I contacted IDM support who have tried everything they have, but no change.

Here is the issue: 1. I open Firefox (Duck Duck Go is my default) (132.0.2 (64-bit) 2. I type "vintage sci fi movies" 3. Click on "videos" 4. Pick any movie (example: The Phantom Planet (black and white but this does not matter) 5. In the Choose How you Watch, I click the left icon - Watch Here, and not Watch on YouTube; also click Remember my choice 6. The movie starts but there is no IDM dialogue 7. If I then click Watch on YouTube inside the movie, it switches to YouTube and the movie starts, AND the IDM dialogue pops up.

As I said, this worked in Firefox/DDG a couple of weeks ago.

IDM version is 6.42 Build 23, full (paid for) version Oct 15 2024 The IDM Integration Module in Firefox shows as Version 6.42.22, last updated Oct 28 2024.

Can you assist please.

I keep receiving notifications I've already dealt with, specifically from Youtube, as of writing this is the third day I've had to deal with them.

The notifications pop up inconsistently, anywhere from 5 minutes to an hour, but when they do pop up, it's a barrage of every notification I've already read since it began.

This may be an issue with Youtube itself or Windows, I don't know.

My Firefox browser is updated to the most recent version. I've previously used ProtonVPN and I've never had any problems. As soon as I updated Firefox, however; there are connectivity issues and pages won't load. I've tested with other web browsers and are able to load pages there while they simultaneously won't load in Firefox. I've tried deleting ProtonVPN and re-installing, but that didn't work either. I reached out to Proton about this and they are looking into it from their end to see if there is a solution, but I'm pretty confident it has something to do with Firefox as other browsers are working as they should be.

Today I was no longer able to stream movies on Amazon Prime or Youtube. I watch Amazon movies most nights, watched last night. Tonight I got a message when I tried to continue watching a tv series on Amazon that I've watched for weeks. It said I had to update Firefox and told me how, but when I went thru the process Firefox said it was up to date. On Youtube I got an error msg. 99,999 . What is happening?

I often receive a 403 error when using Firefox Every time, before this happens, I get the unsafe website warning and then the 403 error when I continue anyway

I am using the latest version at the time of writing These errors only occur on my desktop PC I have tried to replicate this issue on both my phone (Android) and another laptop(Windows 11) but all the websites work normally on there.

I have tried the following, none of which have any effect:

• Clearing cookies
• using Troubleshoot mode
• Restarting
• Changing Useragent
• Using "Forget about this site"

The following do fix the issue

• Using a VPN
• Using Google Chrome
• Running Firefox in another profile

Going through the privacy and security tab and reseting all the settings sometimes works but only temporarily

The following are a few websites where the issue occurs

I am so frustrated. Although I'm relatively computer literate, I cannot find a way to stop that sidebar from opening up on Firefox Browser 133.0. I'm using Windows 11 Pro. I can find no button that allows me to either delete it or prevent it from opening. For heavens sake, not everyone wants all this stuff. I just want a great browser with minimal things to have to deal with. It is irritating to have to deal with this when there appears to be no simple solution to get rid of it. I do not feel comfortable with having to try to delete a profile element. Just give me the button to say I don't want it showing up when I open Firefox on my computer. It can't be that difficult. I use the menu bar at the top of the page to deal with bookmarks. I don't need a sidebar. Give me the option to get rid of it. It will always be there to hit the button on again if I choose to but I know I never will. It interferes with my page. If it isn't fixing something that is broken, and you want to try new things, fine. But give me the option to delete it from my experience.

I did some googling first and it seems to be an on and off issue mozilla has had with years. Anyway, whenever I play a video (be it youtube, twitter, instagram, even gifs on twitter actually) the video will often mess up and become a chaotic jumbled garbled up mess of green with junk artifacts over the video. The audio will play fine. It's like watching a scrambled TV station from a 90s bootleg cablebox, but green.

This issue doesn't exist in any of my other browsers.

I'd love to continue supporting Firefox instead of Chrome, but this is a persistent issue across the entire internet, so it's kinda obvious I need to stop using Firefox until this is patched. Thanks.

Does the Mozilla VPN have an easy to use "on" "off" switch? I want better access to streaming services

But I also want to browse and easily log in to banking, health, and financial sites where i have accounts that are protected by recognizing my current IP address to allow me access to my accounts.

From reading information about the numerous VPN providers, it seems like having a VPN might make it difficult to log in to financial, medical record sites etc.

When open Google Drive using Firefox, I cannot click on any documents. I can open folders but the documents in these folders I cannot open. I can open Google Docs and then access documents but all documents through Google Drive including in the Shared Folder are greyed out and when I click on any of these I get the pop up "This file cannot be opened because you're offline." I can access Google Drive and its documents using Chrome. I would prefer to use Firefox.

I have updated Firefox, cleared the history, and emptied cache and cookies. I also logged out of and then back into my gmail account.

The image shows what the drive looks like when opened in Firefox.
