This is observed on Pixel 9 Pro. Running Thunderbird v21 from F-Droid.

Not sure if this is in the latest update, but if I select a message, the top of the screen (where we are notifications and battery level) turns into a black bar. This happens in, both, the unified mailbox and a specific mailbox.

Is this a bug or normal behaviour?

thunderbrd version 153.0.1 64bit windows11 Spamfilter problem

my contacts are all in the personal address book convinced they get filtered as NOT SPAM, recently some addresses out of my adressbook get filtered anyway - weird an expert told me to setup a whitelist as a subfolder: I did but same prob... as far I know the address book works like a whitelist anyway, no success also not long ago thunderbird had an update - and it feels since the dodgy filtering started. Using thunbderbird for ages - never had that prob ever - till recent

Is there any known solution please ? Thanks & regards Jochen

Mail notifications remains on the home screen and need to be removed manually. I had expected them to be removed after reading the mail or marking it as read. A notification summary with the number of received mails instead of a notification for each mail, as an option, would have been nice. /Sten

When I open my website, pvamarkets.com, I see a Cloudflare page that says:

“Suspected Malware — This website has been reported for potentially distributing malware.”

This is a legitimate e-commerce website. After the warning appeared, we completed a full server-side security check. We checked the website files, database, cron jobs, access logs, error logs, and file-delivery system. We did not find malware, executable files, unauthorized code, or signs of a server compromise.

Our website only delivers plain text files to customers. It does not host or distribute Windows executable files.

I understand that the warning page is branded by Cloudflare, but I am posting here to confirm the following:

Is this warning generated or influenced by Firefox or Mozilla Safe Browsing? Can Firefox cache an old security warning after Cloudflare removes it? Is there any Firefox security report or blocklist entry for this domain? What steps should a website owner take to confirm that Firefox does not classify the domain as malicious?

The warning appears before visitors can access the website and causes serious trust and access problems.

I have attached a screenshot of the warning page.

you have to delete over 5 times to get history and cookies to clear. Selecting "everything" never removes everything :( Used to be the best for privacy now its seemingly deceptive..

I have used firefox for 13 years now and I have never had any major issues with it. but recently I have noticed that whenever I open it on my laptop, the laptop freezes and then a black screen, then a mozzila firefox crash dialog box. sometimes I am forced to hard restart the laptop then use another browser. I still want to continue using Firefox but that issue is really frustrating.

Thank you

Hi everyone,

I'm working on a website that generates and displays Unicode-based stylish text. Everything works as expected in Chrome and Edge, but some generated text doesn't render correctly in Firefox. In a few cases, the characters appear differently or fall back to a default-looking font.

I've already cleared the cache and tested with Firefox in Troubleshoot Mode, but the issue still persists.

Is this a known Firefox rendering limitation with certain Unicode characters, or is there something I should check on my end? Are there any recommended practices for improving font compatibility across browsers?

Any advice would be appreciated. Thanks!

When I frequently turn off my computer using the system unit's power button, meaning a quick shutdown, after several such shutdowns, when I launch the browser, I'm prompted to log in again. Bookmarks that weren't synced disappear. And I'm also logged out of all the websites I was logged into, forcing me to log in again. Cachyos Linux.

The mouse cursor does not highlight text in the address bar. It is selecting the text but the blue 'select' highlight doesn't show so I'm working blind. Firefox 154.0b5 Build ID: 20260731090442 (64-bit) on Windows 11 Home 25H2. Build 26200.8875 Tested in troubleshoot mode - same issue.

No point adding screenshots to show an invisible select highlight.  :-)

I use Thunderbird on my desktop and since early June, I have not been able to receive any new messages but I can still send. Everything works fine on webmail (Yahoo) and phone (Samsung Galaxy), it's just my desktop which is affected . I asked Duck AI about this and this is what I got...

I tried the solutions offered without success.
