I'm trying to install Firefox to my 2012 Asus u57a laptop from a SD card that is in my phone cause the Internet explorer is outdated cause it is on Windows 7 and I am trying to get Windows 10

I am unable to log into my Microsoft account normally. After entering my username and password, when I should be prompted to enter the two-step verification code, the webpage only displays the message: "Please retry with a different device or other authentication method to sign in. For more details, please see this link."

To resolve this issue, I launched Firefox using the -P command to access the Profile Manager, deleted my existing profile, and created a new blank profile. After logging into the new profile, I first signed into my Mozilla Firefox account to reload all my bookmarks. Without waiting for the synchronization of bookmarks and extensions to complete, I immediately visited account.microsoft.com and attempted to log into my Microsoft account, but the issue persisted.

Strangely, I opened a new private window and was able to successfully log into my Microsoft account through it.

I just opened Firefox on my Win 11 pc, and find all my tabs have gone. The setting to reopen last session is active, as before. I think FF updated itself earlier today. I also had occasion to look at it briefly on my synchronised android phone. I would like to: - get my tabs back - find a way to stop this haappening (it's not the first time).

Any advice much appreciated, thanks. Richard

I have a issue with a browser add-on There is a triangle icon with Len dau English: triangle icon - Go to Top I can not find any way to remove or I have know Idea how it was installed

Any help please

I’ve been using Firefox regularly and overall the experience has been positive, but I’ve noticed a pattern during longer browsing sessions that I’m trying to understand better. When multiple tabs are opened and I switch between them frequently over time, Firefox sometimes becomes less responsive. Pages may take longer to load, scrolling feels delayed, and opening previously loaded tabs isn’t as smooth as it was at the start of the session.

What makes this a bit confusing is that system resources don’t appear to spike significantly, and the slowdown seems gradual rather than immediate. Restarting the browser usually restores normal performance, which makes me wonder if this is related to session handling, memory cleanup, or how background tabs are managed over time.

I’m not necessarily looking for a quick fix, but rather trying to understand whether this behavior is expected and if there are recommended settings or habits that help maintain performance during longer sessions. If others have noticed similar behavior or have insights into how Firefox manages extended tab usage, I’d really appreciate learning from your experience.

Firefox has been crashing regularly for a full day now. I have one profile with multiple extensions, and a fresh profile that is meant to test firefox without any. With this new, "clean-slate" profile with none of my extensions installed, I still get repeated crashes. It is getting in the way of my ability to work- it happens even in Troubleshoot mode, even though I could not confirm any hardware issues prior to this.

Will I need to delete the extenstion-filled profile entirely before going forward? Is there an update I need to install, or anything else I should do myself? Should I provide a list of my extensions?

Attached is the Report ID of my latest crash- hopefully it will help.

Thank you!

Per [https://support.mozilla.org/en-US/kb/control-personal-device-local-networ...] I was looking for Settings > Permissions > "Local network devices" but the option was not present.

Looking at about:config network.lna.blocking I found it set to "false" by default. Only after I changed this to "true" did the UI shows the "Local network devices" configuration option.

Why is this disabled by default? Isn't this a security risk? It seems like users should be notified by default and have the option to block these requests.

Hello,

I just installed a new version of Linux Mint (Zara) and all is right with Firefox, except the screenshot who doesn't work. The buttons "Capture the visible area" and "Capture the entire page" don't work. The additional tool in the toolbar doesn't work. What can i do, please? Thanks for your answer. Pierre

Hi,

I have logged out from some device (laptop) today. I had approx 150 tabs over there I would really like to recover. Is there any chance to get them back?

Kind regards Grzegorz

My old laptop computer completely died. I installed Firefox on my new computer. However, after signing back into Firefox, my stored passwords and tabs were not available. How do I find/recover saved login passwords and tabs? I am a long-time Firefox user and had a lot of stored information that I assumed would follow my account.

Thank You,
