cmd+numbers on alphanumeric keys should switch to respective tab (cmd+1 to 1st tab, cmd+5 to fifth...). With CZ keyboard layout on MacOS, cmd+1 does NOT switch to first tab, it Zooms In instead. No other browser (Edge, Safari, Opera, Orion) exhibits this behaviour. Other numbers work as expected.

FF 98.0.2 on Monterey 12.2.1.

How do I fix this? Thanks.

My laptop set-up is practically identical to that of my PC, but the latter doesn't exhibit the same malfunction.

I've tried anything I could, including reinstalling the browser, removing all of my bookmarks (about 10,000) and addressing extensions (Decentraleyes, Default Bookmark Folder, Disable Tab Detach, Flagfox, I don't care about cookies, Keepa, Notifier for Gmail, Privacy Badger, To Google Translate, uBlock Origin, Undo Close Tab, Video DownloadHelper and Youtube's Annotations No More), but not even safe mode improved the situation in the least. Windows Defender also hasn't detected any malware and my web surfing habits are as safe as it gets.

The only deeper data I could gather is that the problem manifests with a progressive, rapid surge in CPU and RAM usage; the former, for example, is saturated to its total 16 GB in a matter of about 20 seconds.

My laptop is a Dell Inspiron 7586 with Windows 11 64 bit; Firefox version is the latest, 100.0, and, by the way, none of the recent updates has improved the situation.

Thanks to anyone who might come up with an educated guess!

I currently have this add-on installed. It allows you to you highlight certain text, then right click and open up a link to Wiktionary in another tab. Up until a few minutes ago, this menu item was at the very top of the list (i.e. above "undo" and all the rest), but now it's been moved down with all the other add-ons. Image for further clarity.

The add-on hasn't been updated in 6 years, so it's certainly not that. I don't recall doing anything to make it change, but before this, it had been at the top of the menu ever since I added it maybe 2 years ago. Is there any potential way to restore this functionality? The fact that it appeared at the very top of the menu might have been a bug, but if that's the case, it was certainly a convenient one.

Anyway, I'll be looking forward to hearing from you fine folks in this community.

I'm trying to take a proctored test with PearsonVue. It keeps saying on the system test that Firefox is still running. I've tried shutting down through Task Manager. I've tried rebooting and just using Chrome to access the test page. It still says it's running. Next step is to uninstall...surely there's another solution!?

suddenly Thunderbird email stopped working. I keep getting a request to input and change my password and have done that several time. I also have gone through all the steps to ensure all the info was correct and connected properly. My email works fine when I login through the internet. Passwords are correct, connection info is correct. My emails work fine on my phone. I have uninstalled the program but it had no effect. I am using version: 102.0.2 (64-bit)

I used to get a display in the middle of a "New Page" with Firefox - recent revisions have removed that and I only get a Google search bar at top of new page. Help is appreciated. What I am looking for is displayed in images from my Chrome browser - similar, but not like the way Firefox displayed it.

I enjoy Thunderbird but it lags, stops, is slow (on more than 1 computer)......Ive searched google and tried a couple of different things suggested but no difference. so before I switch, wanted to see if there are any answers here

My Firefox browser accessed the internet until a day ago. Now its unable to load pages. Computer’s network connection is good. I did a firewall check. I even excluded the browser from firewall checks to no avail. The only alternative remaining is resetting the browser. Any suggestions will be appreciated.

Thanks.

Just now, as I was in the middle of something, Firefox popped up a usage tip about tabs. I find this disruptive. Is there a way to turn these off? If I want to know how to do something, I'll look in the help.

It's fine when you create a new feature to display a tab when I first launch after an upgrade, or to have the Help menu show a Latest Features item, but please don't interrupt my work with pop-ups.

For the moment, I don't see anything in Preferences about this. Is there an about:config setting I can add to suppress this feature?

Thunderbird 102.4.2 (64-bit) running on Windows 11 Pro (22H2, 22621.755) on a Core i5-12600K with 32 GB DDR5 RAM and PCIe x4 SSD. Xfinity cable Internet with tested 90/12 MBps speeds.

Every time I try to move messages from my Gmail Inbox to a folder, Thunderbird stops responding and exhibits extremely slow performance. For example, moving 36 messages took over 34 seconds to actually move the messages, with no indication of any progress during that time, and the title bar saying "Not Responding". 0% CPU utilization during that time, as well.

There is obviously something wrong here. I'm trying to move my messages from earlier this year into folders to resolve clutter, but with a relatively high-end system like this, I ought to be able to move thousands of messages in the blink of a eye.

Hello,

Can you please tell me how to downgrade Firefox Nightly to Firefox Stable Release channel on Linux Ubuntu. When I try to exchange the firefox versions in the snap store of Ubuntu I seem to loose my whole data stored in Firefox.

Thanks.

I am getting a troublesome screen popup after I click Done on the last screen setting up my AOL account in this new Thunderbird. Does anyone know if this is a malware taking over to get my login credentials to AOL? Why would this be popping up when maybe it should link to AOL login directly to check my login credentials? What is this "Castlemedia" link deal to finish my Thunderbird to set up? I added the full hyperlink that shows up at the top of the AOL LOGIN screen for you all to view.

Thanks for any help...from the support group here. Eric S.

I know NOTHING about technology; everything I've read to try to remedy my issue makes no sense to me; I'm not able to follow the suggestions because I can't find the links referred to. Can someone please help?

Some of my incoming emails have become displaying at plain text instead of HTML in Thunderbird.

I have tried toggling View>Display Attachments Inline, View>Headers>All vs. Normal, and View>Message Body As>Original HTML vs. Simple HTML vs. Plain Text. Nothing seems to correct this handful of emails.

When I browse the same emails via a browser at mail.yahoo.com, the appear as normal HTML.

Until this occurred, I had not made any configuration changes to Thunderbird or my Windows laptop.

Thanks in advance for any suggestions.
