Firefox Support Forum

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.

My computer (Windows 11) crashed while I was using Firefox--for the first time that I've seen, it did a full disk check. When booting back up, I was unable to use Firefox, since it said that my profiles.ini file was lost/corrupted.

After renaming the old file, I went back to the folder. It was easy enough to reinstall the add-ons that I needed, but I'm trying to get my bookmarks back. However, I can't seem to find them--the "bookmarkbackups" folders that come up are too new, and only one (the current one) has a file in it.

Any help will be appreciated! I'm not sure what I can do.

As of 2024 06 20 there are many websites that I cannot login anymore one being Facebook with this message:Update Your Browser You’re using a web browser that isn’t supported by Facebook.

Websites look extremely ugly because of the white borders surrounding icons. I've tried using CSS code I found on Reddit from posts that - I think - are related to my issue, but they proved fruitless.

What CSS/Setting do I have to disable to get rid of this?

Firefox 115.12esr slow to startup takes up to 10 second to load the first time now Firefox was fine in version 112.esr. to bad Firefox forces updates, even when the update make Firefox worse. https://snipboard.io/QF0ERT.jpg of course it works faster without extensions, that does not mean anything. I would reinstall the older version but Mozilla fixed so we cannot. I do not have time to reinstall all the extension so I am left with a useless Firefox. To bad Firefox does not allow reinstall of extension automatically, a reset of Firefox would also make Firefox useless; I am at a loss to how to continue to support Mozilla and not switch to another browser?

Hello!

Started up Firefox today and these whited out boxes started appearing over my search bars and random part of the screen, such as the descriptions of different articles on my home pages, extension and theme information in my settings, and different tabs (see pictures 1 and 2). The text is also white, making it almost impossible for me to see what I'm typing or selecting in the search bar (picture 3).

I've already tried some tips that I found on the forums such as changing the hardware accelerator, making sure my extensions and add-ons were up to date, etc. When I go into troubleshooting mode, the boxes disappear and Firefox functions normally, but when I tried turning off all my add-ons and themes on the regular browser, the problem still wasn't fixed. I did a full refresh of the browser, hoping that would help to reset whatever was causing the issue, but that didn't help either.

Any advice or troubleshooting tips would be greatly appreciated!

Over the past week or so, Youtube videos take a while to start, and will at times just stop and buffer. I turned off uBlock Origin for Youtube, and I have Youtube Premium, but this issue is still happening. Ookla speed test is 569.32 Mbps download, and 23.50 Mbps upload. My Firefox is set to automatically update. Current version is 127.0.1

Automatic update on my Windows 10 desktop of the the new update 127.0.1 resulted in a version of Firefox that worked more or less for some web sites but was unable to reach others.'

Hi, I would like to know which version of Mozilla used this setting of network.trr.excluded-domains: 'sbl-xbl[.]spamhaus[.]org, localhost.that.never.exists'. The default is 'undefined' as I checked in 127.0.1 and the older 124. I also contacted support of extensions that I used, no evidence of both excluded domains. Can anyone help me? Thanks a lot \!o!/

I had a crash on my SSD (WIn7 Ultimate) - " Operating system missing" error. I saved the data and want to reinstall Win 7 and import previous Bookmarks data to new install of Moziilla Firefox.

I transferred the sqlite file (s88qn337.default) from the previous install (now non working system) to the existing working Firefox directory (C:/Users/My Name/AppData/Roaming/Firefox/Profiles/xxx.default.

I then renamed "default.XXX.old" (the previous install had only one file in the Profile directory - ie s88qn337.default)

When I try to open Mozilla Firefox, with the single file (s88qn337.default) in the Profile directory, I get the error "Can't find user data".

When I then open fresh install of Mozilla Firefox on working SSD (Win 7 Ultimate) and try to Import Bookmarks, the options are only "Import Bookmarks from Explorer" or "Import from html file".

How to resolve this problem, please?

I have an issue with Firefox 127 not accepting a session cookie that I use for user authentication. I have an ASP.NET application with a login form that includes fields for login and password, and a submit button. When the button is clicked, an HTTPS/POST request is sent to the server. The server responds and sends back a session cookie named .Cookie.Name with the parameter httpOnly set to true.

When I check in Firefox's Developer Tools under the Network tab, I can see .Cookie.Name in the server response. However, in the Developer Tools under the Storage tab, .Cookie.Name is missing, which prevents the user from logging in. This problem does not occur in other browsers like Chrome or Edge, nor does it occur in Firefox version 126. The configurations for Firefox 126 and 127 are identical.

Could you please assist with this issue?

Dear friends,

Can anyone say why this is the case?

Kind regards Uwe

I'm trying to get my Firefox installation to permanently disable private browsing mode, however, all information I can find is for the Snap version of Firefox, and not for the Flatpak version. How do I disable private browsing on my installation?

Hello, today I decided to create a new Firefox Profile. I set the directory of this profile to be my desktop, which is where I usually put things (downloads and such) by default. I thought it would create another folder there on the desktop and put everything inside that, but instead it put a bunch of junk on my desktop. No big deal, right, I can just delete the profile, and that other junk should also be deleted. Well, not only did deleting the Firefox profile delete the extra junk that was created while making the profile, it also, for some reason, has deleted about 90% of everything else on my desktop as well. There are now only a few seemingly random things left on the desktop, that it decided to spare for whatever reason.

Where did everything go? The recycle bin is empty.. Most of it was just shortcuts, not a big deal, but I did have a few folders with some rather important work that I would very much like to retrieve. Please tell me Firefox didn't just nuke my desktop, and that all of those things are now unrecoverable? Windows 7 64 bit

Thanks very much.

I just asked a question about email not downloading to thunderbird and got an answer which I think meant that this was not the place to ask. I cannot find an open question place in Thunderbird. Where can I get support?
