I apologize for the unhelpful summary line, but I am totally new to Thunderbird and the Unified Inbox is acting so strangely that I don't have any simple way to describe it.

Many (but not all) of the emails are displayed twice in the list of messages.

When I delete a message that isn't doubled, the message disappears from the inbox (as it should).

But when I delete one of the doubled messages ONE disappears as it should and on the other Thunderbird clears the From and Subject fields and changes the date to 12/31/1969, 19:00 -- the changed entry stays in the list and the body of the email is still shown in the lower pane. The only way I can get rid of the message is by selecting another folder (ANY other folder) then when I return to the Unified Inbox the deleted messages will be gone from the list.

I can't believe that this is how Thunderbird is supposed to work, so I assume I have something configured incorrectly (although nearly everything is still at the defaults that the installation gave me).

In the last few weeks, i cannot read my iCloud emails. It says things like"message cannot be downloaded now" or "cannot move to trash now", so the only way I can consistently read my emails, is to switch to my Google browser, which has absolutely no problem with the iCloud emails Why would this be happening?

When using vertical tabs layout with "expand sidebar on hover" setting enabled, sidebar scrolls up with each expansion, so that when hovering over a certain tab of collapsed sidebar, another open tab is under the mouse pointer when expanded. For additional details please refer to the attached video.

Steps to reproduce: 1. Enable vertical tabs layout with "expand sidebar on hover" setting 2. Open a lot of tabs 3. Hover over a certain tab

Observed result: The sidebar expands with mouse over another tab and the list of tabs scrolled up.

Expected result: The sidebar expands and mouse pointer is hovering over the same tab after expansion from collapsed state.

I am having issues where pages I open will show it continuously opening (Page load status on tab keeps bouncing even when page is loaded) some page I need to try a couple times to load content. This seems to have started when I upgraded my Mac to OS 2.6. Currently I do not have any extensions or themes to troubleshoot. I did try in troubleshooting mode and everything worked fine, but all the documentation points to themes. I have tried clearing cache, quitting, restarting my computer it always comes back. Is there anything I can do to stop this otherwise all my work on Firefox will have to be moved elsewhere. Below the guess about my OS it says my OS is 10.15 which is incorrect it is Tahoe 26.3. I am not sure why this would come up as a 2019 OS.

Best,

Gina

I've followed all recommendations to fix that, but nothing works. Should I remove the browser, boot up, and download it again? Remove all my personal settings, etc? Also, I download my emails, I erase the unwanted emails, and suddenly, many copies of my previously erased emails show up after I get a new email. This happens with Gmail and Yahoo Mail. Please help me, this is driving me crazy and taking up my time. Gratefully, have a swell day! Isis

While testing the new profiles option with Firefox after loading containers while having Surf-shark VPN on my computer stop accessing websites. The conflict was resolved by reloading surf shark and then while attempting to remove new profiles not being used I deleted the original homepage/profile. Over 10yrs of bookmarks, passwords, and numerous pieces of data have been lost. I need that original Firefox homepage user account for my computer restored.

I use a Lenovo desktop computer that I have used along with the Firefox browser for about 3 years and never had any problems until now. For the past two days it takes up to a couple of minutes to for the Firefox browser to open a page. While the page is loading, I get at the bottom right corner of the screen "performing a TLS handshake." I vaguely understand this terminology but am not an expert on the subject. This "handshake" repeatedly occurs with all sites that I open daily with the Firefox browser. The pages usually open within a couple of seconds. Now it takes minutes and sometimes doesn't open at all. I have difficulty opening even the Firefox home page and when it finally opens, it is incomplete? Do you have any suggestions that might help me?

I must add that the internet connection from my provider, Eastlink, located in Nova Scotia, Canada, is by Ookla tests very slow, ranging from 40 to 55bps instead of the regular150bps or higher. I don't know if the problem is with my desktop or with the provider and the provider has not responded to my telephone request with any information that explain where is the source of the slow internet speed problem.

Sometimes, I cannot click on an option on a form (on my up-to-date Firefox, on Windows 11 - help, please! Its usually only when the options are shown as little buttons or squares to tick off. Its not my mouse because it works for the usual mouse works.

I can't enter the tick/click necessary on this form to say "Email me when someone answers this thread" Cheers, Carol

Hi everyone,

I’ve been testing a simple online click counter to track clicks and sometimes test my clicking speed. The tool works fine most of the time, but in Firefox I noticed that after refreshing the page the counter occasionally keeps the previous number instead of resetting to 0.

This is the tool I’m testing: https://thetallycounter.com/

I’m not sure if it’s related to Firefox caching or local storage behavior. Has anyone experienced something similar with web tools that store values in the browser?

Would clearing cache or disabling something fix it, or could it be a Firefox-specific issue?

Thanks!

I'm trying to switch from Thunderbird ESR (140.8.0esr) to release (148.0). Following the Mozilla support recommendation I'm running the 148.0 setup and trying to install it to the same directory. While doing so I'm asked to restart the computer. After doing so I'm required to restart setup but continuously asked to reboot the computer. is there a zip version of the installation? if not How to overcome the restart issue?

Due to an internet outage, I got forcibly signed out of my Firefox account. I signed back in, but all my login info and passwords are just gone. I still have my browser history, and I'm even still logged in to some of my accounts, so I know some of my cookies and cache are intact.
