Hello,

Based on this previous post https://support.mozilla.org/en-US/questions/1195138

I have turned off mousebutton.4th.enabled and mousebutton.5th.enabled

But I wish to bind these buttons to previous tab / next tab How can I accomplish this ? Thanks

I just installed Firefox on my PC haven't had it on this computer since reinstalling windows - I imported my bookmarks and passwords from Edge, thinking it would be a seamless transition, since I used Firefox in the past without much trouble.

Two weeks on, about 95% of every page I open gives an error similar to the one below, and I have to shift+refresh several times to get it to reload before it goes away, (some sites still don't open).

I wonder how common this issue is, and how people fixed it?

Be careful. Something doesn't look right.

Firefox spotted a potentially serious security issue with connect.mozilla.org. Someone pretending to be the site could try to steal things like credit card info, passwords, or emails.

Advanced What makes the site look dangerous? The site is set up to allow only secure connections, but there's a problem with the site's certificate. It's possible that a bad actor is trying to impersonate the site. Sites use certificates issued by a certificate authority to prove they're really who they say they are. Firefox doesn't trust this site because its certificate isn't valid for connect.mozilla.org. The certificate is only valid for: *. eero.com. What can you do about it? Probably nothing, since it's likely there's a problem with the site itself. Sites use certificates issued by a certificate authority to prove they're really who they say they are. But if you're on a corporate network, your support team may have more info. If you're using antivirus software, try searching for potential conflicts or known issues.

Proceed to connect.mozilla.org (Risky)

I have selected the 4 rows for shortcuts on my tab and have installed all but the last 3 spaces in the end of the 4th row. There's no option whatsoever to continue to add those remaining 3 spaces. Any suggestions?

I cannot get access to my mail cpimtrp@gmail.com. the system asks me to turn off VPN . What to do to open the mail

Hello,

I have dark reader installed, it makes every website dark mode quite efficiently.

However, it cannot make *.mozilla.org dark because those are restricted pages that addons cannot modify.

Even though I have enabled "restricted pages" in dark mode, it does not work.

Here are several more discusions requesting this

После обновления Файрфокс,перестала работать веб версия мах.Будьте осторожны. Что-то выглядит не так. Firefox обнаружил потенциально значимую проблему с безопасностью web.max.ru..В других браузерах оно работает.

Firefox has been automatically updated on Windows 11 and Tahoe, and now every time I close the browser, all tabs close – even the pinned ones – despite the ‘Open previous windows and tabs’ option being selected at startup.

I really can't add to my Summary other than it's a fairly recent issue, started in May 2026, possible April. About.config is set to False. I hope some has a solution - it happens when I'm dealing with live incidents.

How can I log in to my firefox account to sync on my new PC if I can't verify the email address associated with my account? I no longer have access to that email because my employer phased it out.

Being a weird person, I always saved my sites on my firefox browser and for my own reasons, hadn't bookmarked them and always kept them open on tabs to pick up and read at a later date, and as a result, racked up a lot of different tabs that were all very dear to me. However due to a catastrophic hardware failure a few hours ago I lost everything on my local files, including my backups of all the firefox tabs. I was hoping that if there was a remote possiblility that if the sync was able to record tabs, that it would also save all tab information from previous browser sessions.

After Windows 11 Home's Microsoft password manager supports passkey, I have troubles with passkeys in Microsoft password manager, not Windows Hello.

1. Firefox failed to login into sites with passkeys in Microsoft password manager tied with sites.
2. After Firefox added a passkey into Microsoft password manager (at that time, no error occurs and display succeed messages), Firefox an Microsoft Edge (Chromium based) fails to login by the passkey. And this trouble continues after Edge replaces the passkey tied with the site.

So, I can't use passkeys in Microsoft password manager.

Have you heard something like this troubles?

OS: Windows 11 Home 25H2 (Japanese locale) Firefox 151.0.3 (x86_64 with Japanese locale. On second trouble, I used the latest version at the old time) Edge: 149.0.4022.52 (Official build with Japanese locale)

Hey hey So On my old system I logged into my FF account did 7 syncs just in case whi all were telling that I'll have all of my stuff right away but.... I reinstalled Windows and... installed Firefox and got freaking 00000000 zeeeero tabs or passwords synced.... All of the manual attemps of sync got nothing, absolutely nothing!? So what was the point of online account which does nothing and just give a fake faith??? I would rather do cp -r of local foler as I did for the last 20 years.... But this time I was faked with fake "sync all good" which doesn't work and just fake people
