Ondersteuningsforum voor Firefox

I'm using Firefox 96.0.3 and Twitter will not load. Blank page. It's working on another browser. Help would be appreciated, hopefully something simple as I'm not very tec minded. Thanks

Dear TS, Friday January 28th 2022 Firefox updated my Win 10 PC to version 96.0.3 and wiped out everything from the previous Firefox version. No bookmarks, History, or add ons, everything is gone! How do we get everything back? I have a recent backup using Acronis on an external drive and even copies of old profiles from 2016. If the data can't be retrieved I'm thinking the only option is to remove Firefox and attempt restoring it from the Acronis backup. Sincerely, Robert.

When browsing to mail.yahoo.com I get the following error: Secure Connection Failed

An error occurred during a connection to www.sportsmansoutdoorsuperstore.com. PR_CONNECT_ABORTED_ERROR

Firefox has been running fine for me for a long time but recently, like the last week or so, it has been crashing constantly. When I first boot up my computer, it will be fine for awhile and then it'll just crash. If I try to restart it then, it will either immediately crash or crash after a few seconds. sometimes it will hold together for a bit and then crash. I've had it crash when I've clicked to move to a new webpage, and I've had it crash when it is just idling on a webpage. I have already tried troubleshooting mode and it still crashed, so its not my extensions. Ive also tried to reinstall it and that has not helped either. Any help would be greatly appreciated.

I installed multiple language dictionaries for spellchecking from the "add dictionaries" menu. Despite this, after restarting the browser (and the computer) multiple times, no matter what I do, they don't show up in the spellcheck menu, the only option is still default "Polish" (language of my operating system). This is really annoying as I practically don't use Polish internet, so I would like to get English spellchecking. I even changed the Firefox interface language to English, but it didn't do anything.

My Digital Check CX30 Scanner has a communication error come up when trying to scan checks. This only happened after the latest update. I called the bank and the scanner is not the issue, Firefox is the issue. The scanner works on Chrome but I'd rather not use it. Tried uninstalling and re-installing Firefox. Added the website to the exception list for blocking pop-ups, added it to the trusted sites list in ublock origin. Still doesn't work. My IT guy is stumped. Any ideas would be greatly appreciated.

Thank you.

Twitter shows up as a blank (white) page. Cannot login. Works okay in Chrome. Got these msgs for Firefox Inspection tool.

I'm running 96.0.3 on a fully patched Win 10 Pro system - both O/S and programs. When Firefox is running I'm getting these pop-up error messages randomly with changing content. They stay on screen for some seconds and then go away. Message states it's from (via) 5.back2yard.biz. I put that in my hosts file and I'm still getting them. My network is a cable modem hooked to Xfinity and then cable connected to another fully newer patched router. All addresses are 10. range. I ran both a Malwarebytes scan and a Windows Security scan - both are clean.

I'm unable to upload a small image after a hour so I'll give up on that right now.

Well my problem is exactly the same as in this post: https://support.mozilla.org/en-US/questions/1256699 My Firefox and my Widevine are both on the newest versions, I have this problem only with Firefox and its been that way for a while now, but it got too annoying so I'm posting about it now. The errorcode is also the same is in the other post (F7703 - 1290). This error also isn't findable on the official Netflix help side. It only affects Firefox refreshing the page or coming back a month later it doesn't matter it never works in Firefox anymore it used to work. In any other browser or in the app it always works. I also tried to disable all my addons and it didn't help. I hope it will be fixed someday, bye.

As of recently, Firefox adapts some elements (basically everything in the toolbar, like the downloads or browsing history) depending on whether it identifies the theme you use as light or dark. I am using a custom theme (this one: https://addons.mozilla.org/de/firefox/addon/tardis/?utm_source=addons.mozilla.org&utm_medium=referral&utm_content=search) that Firefox identifies as dark, however I absolutely hate any form of dark mode. So far I figured out how to force Firefox to use a light theme everywhere else using about:config, but I couldn't figure out how to change the abovementioned elemtents back to light without changing the theme. So is there any way to declare a theme as light or some other way to change this behavior?

I added a plugin that enabled privacy.clearonshutdown for a number of settings and I have lost my Cache and History. Is there a way for me to restore that data? I haven't restarted my computer yet.

I was looking at other options: https://support.mozilla.org/en-US/questions/1290163 and apparently there is an index.dat thing I could use as well, but I can't find it. I really can't afford to lose yet more data after my last mistake.

Following a VERY troubled update to Windows, which required several hard shutdown/reboots, invoked an automatic attempt to repair Windows, reported that the repair attempt failed, but then booted into Windows normally, the only thing that seems to be wrong is that certain websites report "Secure Connection Failed" with an error code PR_END_OF_FILE_ERROR. Contrary to the support page, there is no option to report this to Mozilla; the only option is to retry. When I click retry, I get the same page with the error code PR_CONNECT_RESET_ERROR. This is not a problem with the website -- same website works fine in Firefox on both other computers in house, one running Windows 10 and one running Windows 11. This is not a problem with the operating system -- I have used both the system file check and distribution manager to check/repair Windows system files, and also successfully accessed the web page using Internet Explorer (Microsoft Edge is disabled in Policy Management). So this is clearly a problem with Firefox. I attempted to reset Firefox, but it didn't help. I then uninstalled Firefox, and attempted a clean re-install; I'm not sure how clean the reinstall was, because it detected the prior installation, and imported things. The sites I can't access include Wikipedia (of all things!), some links in the Firefox support pages, and my on-line banking website, which is pretty critical. Other websites work just fine, including most of my other financial accounts -- credit cards, etc. HELP!

After this last update Firefox is really slow loading pages and has crashed on me multiple times, I have also noticed if the browser is up it slows other programs down now like when im burning a cd. Is anyone else experiencing this? Thank you

PC running Windows 10 hard drive failed, rebuild did not have Firefox. I downloaded latest version, but it showed up with older version of bookmarks. Before HD failed had saved a later version in both HTML and JSOP (???), to a thumb drive. How does one replace current bookmarks with the newer version from the back up drive. Did not know that Firefox automatically does back ups. Thanks,

Hello, I've notice for the passed couple weeks that Firefox 96.0.3 (64-bit) Windows 10 (64 bit) bit is refreshing several of the website pages automatically example would be several social sites it is when I'm typing messages it refreshes and I end up losing all my information. Just today another website Consumer-Reports it did the same thing. I've never experience this in the past. Any solutions, please?

Thanks, David

I cannot use Firefox to browse any more, because it refuses to load gmail and/or youtube. These are sites I have used thousands of times in the past, but recently Firefox will not let me go there any more, and it says "secure connection failed." It also says I should "contact the website owners" to inform them of this problem. (Good luck contacting Google!) Seems like this must be an error, since I have used those sites many times in the past. I have looked at this page of Mozilla's: https://support.mozilla.org/en-US/kb/secure-connection-failed-firefox-did-not-connect But it is too long and technical for me to deal with. Anybody have any suggestions about how to get Firefox to not freak out when connecting to a Google service?
