Firefox Community Forum

I have started receiving a secure connection failed error message for a portal log-in website that worked fine for the past 6-7 months (see attached document). Other people in my group use Firefox and Bitdefender to access the portal and none of them are having this issue.

I originally believed the problem to be my anti-virus (Bitdefender) and worked with them to resolve the problems. After trying various solutions including clearing my cache, using private mode and turning off different components of their software, Bitdefender believes the problem is with my browser setting and not their software. I also tried accessing the portal using Chrome in both regular and incognito modes and cannot access the site which would seem to rule out the problem being a Firefox browser problem but contacting Firefox support seems to be the next logical step.

I have been to the Firefox FAQ and saw similar problems with potential solutions - DNS over HTTPS, TLSKEYLOGGING issues, add-on exceptions - none of which worked. I have the most recent version of Firefox and am running Windows 11 home version.

Sometimes if I hit refresh after receiving the error message, the browser will try to connect and I will get a server time out message. If I keep hitting "try again", sometimes the portal log-in screen will appear and allow me to log-in. The key word is "sometimes" since often I just keep getting the server time out message.

Any ideas for me to try from this forum?

When i try to access to the net with firefox and the VPN is actived, i can't. it's searching but never finding. If i desactivated the VPN, it's work. The problem is here just since a few days. Before it was working

how do I get rid of these annoying webpages that appear automatically when Firefox or it's adblocker has updated? it's like advertising for an app I already use the whole time.

thank you, blue

Firefox stopped working yesterday. When I open it, it immediately crashes. After multiple times of that I refreshed it as it asked. It then worked ok. However after closing it and coming back later, it again immediately crashes. I then tried uninstalling and reinstalling, but it still does not work.

Hello! My Firefox browser is currently in a state where all fonts/letters in the Firefox interface (bookmark bar, settings, about page, website name...) are replaced by undecipherable characters.

I've searched for similar problems already and tried so far the following steps to resolve, unsuccesfully...

• Opening the browser in Safe Mode / Deactivating all extensions
• Uninstalling and reinstalling Firefox

• Disabling hardware acceleration
• Trying on another profile




When I copy paste said text to another window (ex: Notepad, Chrome Browser…) it appears properly. And as you can see in the screenshots below the text in actual websites is readable -- only the browser's interface, setting, address bar... are scrambled.

Does that bug rings any bell? Do you have any other troubleshooting steps I should try to resolve this? Any help will be appreciated! : )

Since a few days the free VPN in Firefox doesn't work anymore. When I activate it and try to load a website, i get the message: Connection with VPN failed. Try again in a few minutes. It also says, that my connection is possibly not private and that an app can possibly see my data traffic. The VPN always used to work fine, and I didn't change anything.

I had an automatic update to my Firefox browser desktop yesterday to version 155.0. I didn't notice any issues at the time, but that was because I was using my bookmarked websites rather than looking up anything on the search bar. My keyboard input worked just fine and I had issues.

Just now, I was tried looking something up on the Firefox search bar and it seems that nothing I type into the Firefox search bar worked. I can't use commands either, I tried to copy paste and it didn't work.
