Firefox Support Forum

Every time I enable Light theme for taskbar it becomes disabled & reverts back to Dark Theme. This is not great for my eyesight. Why does Firefox force dark theme?

When I open Firefox (with administrative privileges) lt won't stay open, it just looks like it going to load my previous season (at least that's what should happen), but after a few seconds it just stops and closes, all at once? Also, I should mention; Firefox is updated, Using Windows 10. I've tried to trouble shoot a little . . .

— Reinstalled Firefox. — I manually delete the files in Startup Cache by navigating to the cache folder in your Firefox profile. — Reinstalling Microsoft Visual C++ 2015 - 2022 Redistributable x86 and x64.

Now, at one point it did open, and I decided to refresh Firefox (removing extensions and restoring to default settings) by going to 'More troubleshooting information' option, then clicking the Refresh Firefox button. Closed it, restarted my laptop, and Firefox, added my usual extension / add-on. (I was thankfully able to save my bookmarks or back them up).

When I was done, I closed it. But when I try to open Firefox, lt won't stay open, it just looks like it going to load my previous season, but after a few seconds it just stops and closes?

Should I just remove Firefox all together from my laptop, and reinstall it??

A little while ago I noticed that the site I used to test my gamepads (hardwaretester.com/gamepad, formerly known as gamepad-tester.com) stopped working properly. I just assumed this was either something outside of the browser or the website itself was broken. Today I just tested with several other websites and browsers and confirmed that Firefox seems to be the issue. Even in Troubleshooting Mode it was completely broken.

L1, R1, R2, Triangle, Share, Options and the Left Stick seem to be the only things that function properly currently, with the DPad not doing anything and the rest of the face buttons/triggers hitting the wrong buttons. In the case of the right stick, L2 for some reason controls the vertical movement while the physical right stick still works horizontally. This controller works perfectly on the rest of my system, windows sees the proper buttons being pressed and games that support Dualsense work fine without any interference.

Below I have attached two images which show how the website I mentioned used to look, and the second image is how it looks now. I have a feeling some kind of update to Firefox's Gamepad API has broken this, somehow.

Hello. I am not familiar with this end to end encryption that Facebook now does for Messenger but now when I try to use Video Calling/Chat it tells me it is not supported by my browser, Firefox. I have never had any problems with it before. Is there a fix? Thanks

Filled out a form on a Japanese Retail Store website to contact them and couldn't send the message. Message just hung up all day. I think the connection is secure (icon next to Firefox address bar does not have a slash thru it so I think connection is secure). That Firefox icon says it is blocking trackers and cookies on the website and "Enhanced Tracking Protection" is "On". And got message in bottom corner of website saying "ERROR for site owner: Invalid domain for site key". Using up-to-date Firefox browser, Windows 10 and Windows Defender Firewall. (Tried Windows Edge browser and it said connection was insecure so I followed steps to connect to it like changing Privacy settings and switching to a Private Window but it didn't help.) What else can I try to use this Japanese website? (Note: website does not have an email address listed anywhere.)

So, I installed a new hard drive about a week ago and while re-installing things I also re-installed the Firefox Browser 64- bit. Strangely, it seems like the files did not install itself in the right areas or the files installed did not install themself in the right or normal places. It does work, but for some reason I don't see it's program files? Is this normal or something that happens?

Anyways, I've backed-up my bookmarks, and I am going to uninstall it, re-boot, and re-install it and see what happens I guess. Or should I uninstall Firefox and its Profile Folders also, etc, and than re-install it?

results found for ‘Avast has found a malware software on my computer & is blocking firefox from opening it. Which is fine. But how do I totally delete this? The url is https://quicklivenews.com/news/images/fav_news_search.ico and the threat name is URL:Blacklist. The Process is C:\Program Files|Mozilla Firefox\firefox.exe and was detected by Web Shield. I've rescanned my computer & have run CCleaner. HELP!!!

Whose idea was it to popup a Firefox promotion window while I was working on a text? The popup took me out of the page where I was working, Google Voice. I am struggling, doing this with one hand while the other is in an Ace bandage with an ice pack on top. This was a needless interruption!

Roughly 90% of the time I am using firefox to access and export excel files from a site used for the back end of our point of sale system, the tab I am exporting from jumps to a random URL (usually for a utility company I use to pay utility bills through). I have to go back several pages to get back to the original. It is totally problematic, and fairly random and often the utility company URL will vary; sometimes it's the gas company, sometimes it's the power company....occasionally the internet service provider).

the only autoplay setting i can find is under privacy and security. the page shows DEFAULT FOR ALL WEBSITES: Block Audio and Video, but videos still open and play. the page does not retain the change when i select the button REMOVE ALL WEBSITES. this problem has not been happening for years. it may have begun about six months ago. thank you for your time

Hi, Before I try to refresh Firefox to fix an issue with Youtube pages not loading properly (I've tried everything else), I need to know whether or not my open windows and tabs will be preserved. Thanks in advance!

In Windows 10, Audible throws this error:

An Error Occurred An error occurred during processing. Please close this window and try again.

Other browsers are fine. Other media in Firefox such as BBC Sounds are fine. I cleared the history, then reset Firefox. I thought it might be an issue with the latest Realtek driver, but I could not roll back all Realtek drivers. So I installed an Asus DS Xonar 7.1 PCI soundcard. This shows exactly the same problem.

Thankyou.

Hello,

I am unable to access x.com, and I think this is caused by hackers.

Below I try to explain the facts (or information) that leads me to this conclusion.

After I enter the x.com in Firefox's address, in the developer drawer Network tab I can see the content-security-policy as:

Also, the developer drawer Console tab issues this error before being redirected to x.com/account/access:

I think the HTML that loads in Firefox is corrupted or tampered.

Could I get some feedback?

Hello,

I am unable to either log in or access accounts on the websites indeed.com, x.com and chatgpt's openai.com

I used different computers (Windows 10 and Windows 11), different networks (Public library and private residence), and different versions of Firefox (125 and 126.0), one browser without any add ons and another with the "uBlock Origin" one, and I kept observing captcha or human authentication related errors.

With x.com, I would pass the human verification challenge (solve 10 puzzles), and then I would get the error "Something went wrong. Due to a technical issue, we couldn't complete this request. Please try again." I recorded my screen, and here you can see the video: https://web.archive.org/web/20240604035149/https://trello.com/1/cards/665e5d995d2e821054d66ac5/attachments/665e638096e76922e1404bd1/download/DISABLEMENT_-_unable_to_log_into_X_despite_passing_10_step_captcha_-_Screen_Recording_-_Made_with_FlexClip_-_20240603T172000PDT_-_shortened.mp4

Could I get some feedback?

Thanx

Just lately after decade plus of using Firefox I am getting computer hung up, nothing running but Firefox with 7 tabs open. That is how I been running FF for years, same 7 tabs open and no problems until a coupler months ago. I am on Windows 10 64 bit current with May updates, 12GB main memory, Intel Core i5 @ 3.20GHz, 500 GB WD HDD. The task manager right now is showing 49 FF processes running. All is well right now, but maybe by end of day or tomorrow it will hang up. Right now Virtual memory is set at 14838. I have it set at automatic manage paging file. My hard drive has 281 GB free space. Below is a warning error I see when FF hangs and sends in a report.

Windows successfully diagnosed a low virtual memory condition. The following programs consumed the most virtual memory: firefox.exe (9264) consumed 41230716928 bytes, firefox.exe (1824) consumed 1195388928 bytes, and vmmem (1768) consumed 515567616 bytes.

BTW I am on FF 126.0

When I am on YouTube's website if I click (or right click) and of the other YouTube video links Every link on the page opens up. This doesn't happen if a use any other browser.

Firefox browser not working right. I can change about 3 screens than it just spins back & forth it wont chage half to close & open back up to get it to change crome dont do that & the slide bar on side dont work when you change screens wont go back to top poor service fixing it

This is an utterly bizarre issue, and I don't know if it's my fault. On most web page I go to, when typing in an input field, each time I press A, whatever my mouse cursor is hovering over is clicked. This is extremely annoying and inconvenient. I may be searching google when I'm redirected back to the google home page. I might be typing in duolingo when the question is suddenly submitted and I am marked incorrect. It's a major inconvenience and I have no clue what could be causing it. It's only in firefox, not any other browser. It's only in web pages themselves, not in the url bar.
