I recently upgraded FF on this computer and can no longer sign in to my att.net email account, although I was able to sign in on another computer on FF earlier today. I just get an error message and Att can't help...is there a setting that has me locked out? I can also access email on other browsers just not the FF version on this computer.

Why does Firefox intermittently fail to connect to the Newsmax website? I get a Secure Connection Failed message. It happens only occasionally, but enough to be an annoyance. What's the problem and how do I resolve it?

Hello developers;

I have used Firefox for long time on both Mac and Windows.

Recently, I have been experiencing the phenomenon described above, i.e., when entering Japanese text into iCloud Memo on Firefox, it appears as a double character. I'm sorry but I haven't taken screen shot.

This is the same on both Mac and Windows. It does not depend on the Japanese input method (IME). Refresh and reinstallation did not resolve the issue. Finally, I reverted to the previous version and the phenomenon was resolved.

From the above, we assume that the problem is caused by some kind of recovery in the latest version.

Thank you in advance for your confirmation and response.

The new native tab group feature has an option to "Save and close group", implying that you can restore the group. But doing this, you will find that the group disappears.

Is this a known bug? Has anyone figured out how to restore a saved tab group?

I use several browsers and when it comes to functionality I consider FFox to be the best however with 1 major drawback - it's speed / lag issues which is why I stopped using it as my primary browser and only as secondary one

I can have 2 different Chromium based browsers open simultaneously and while this impacts the performance somewhat if I open Firefox and another browser responsiveness grinds to a halt (sometimes even crashes)

Even just starting Firefox by itself takes 5x as long as other browsers

So I'm wondering is Firefox just more resource intensive or is there something wrong with my setup?

The main difference between my Firefox install and my other browsers is the number of Bookmarks (10000s) due to me having it installed for much longer so is it possible for a large number of Bookmarks to slow the browser down even when not open ?

Other possible causes I read elsewhere are 'Cookies and site data' (currently around 50mb)

I clear the 'Temporary cached files' & 'Browsing history' on regular basis so they shouldn't be an issue

The add-ons I have installed are NoScript , Ublock Origin & Firefox Color

In regards to troubleshooting is it possible to install a 2nd install on the same system simultaneously without overwriting the current one ?

Thanks

Over the last 6 months, and increasing number of websites don't open on Firefox. I've noticed it most consistently on any of the wikipedia/wikimedia pages, but it's not just those. When I type in an address and press return, or click on a link, the browser just acts as if nothing has happened. There does not show me the loading symbole. If I ask it to open a new tab with the site, the address appears on the tab, but the page itself is just black. Other browsers have no problem loading the same sites. I am on a mac, and using a VPN. Restarting the browser doesn't help, though restarting the computer sometimes does.

Thank you,

the tab groups feature doesn't work. WHen i drag one tab onto another, nothing happens, other than the tabs go back and forth. Can't put one tab over another and no group is created.

I reinstalled windows yesterday. When I installed firefox and signed it, everything was fine. However, this morning, it seems to have removed 80% of my bookmarks. When I try to restore from the bookmarks yesterday, it just gives me the ones that I have this morning. I had tons and tons of resource bookmarks for my work that would be almost impossible to re-find in some cases due to the current state of search engines. Is there any way to salvage them? It seems like sync believes they never existed, but it DID sync them yesterday??? Please help.

Since new update was installed today, in touch screen mode, every time a touch a link of any kind my touch keyboard pops up. This is very annoying. Where can I find the setting to turn off this option?

Starting today, if I use google search in Firefox it ALWAYS says i am robot and I have to Recaptcha puzzles. I have done everything with my computer, cleared cache/history, rebooted router/chose "No Proxy" for Internet access/ and searched for viruses/malware etc. Using latest version of Firefox 138.0.1 I am also already logged into my Google account. Dont have this issue if I use google with other browsers such as Edge or Chrome. on a Dell PC using Windows 10.

I dont want to switch browsers but dont know how long I can put up with this. Wouldn't be surprised if Google did this on purpose to entice Firefox users to switch to Chrome.

Please HELP

Windows 11 - 64, Firefox with last upgrade, https://www.flightradar24.com not working. Other browsers (Edge, Chrome) do not have this problem. Other pages Firefox open normal....

About three weeks ago Google Calendar became completely illegible in Firefox. Everything appears in a miniature font. All my other Google applications--mail, docs, voice, translate--operate as they should.

Suddenly [with most recent firefox update?] Gmail is now in dark mode, and some of the emails show very light gray type and are unreadable.

My win 11 is set to light mode, and in about:config, the 'layout.css.prefers-color-scheme.content-override' is set correctly to 1 [lght], and oddly, it won't let me change it.

Gmail opens correctly in light mode in Edge, and also duckduckgo.

Firefox is my primary browser, and if I can't remedy this, i will need to switch  :-(
