Hello! A site kept popping up a confirmation window for an action I was trying to take, and in the confirmation window, there was a checkbox for something like "don't allow [this website] to prompt me again" (that's as best I can remember). I checked the box thinking it would just allow the action to happen without the confirmation window, but instead, the site just won't take that action anymore. How can I undo this setting? Thank you!

Today I updated my Firefox Developer Edition to version 89.0b2 and now I just can not look at this browser anymore, "Inspired new tab design" is taking too much space and now became largest and at the same time least information-dense panel in my entire desktop! I searched around the web for a bit in hopes that I will find a theme or an add-on that will revert this particular change but no luck. I really want to revert to old UI look (at least tabs bar), there should be default theme or option to get back to old style. After some investigation I found userChrome.css but don't really want to install it (maybe this is actually the way of doing this kind of styling). Please help me revert UI design to old one.

Suddenly, Thunderbird 78.9.0 (64-bit) Win10 is very very slow

I don't want to reinstall and have to redo all my settings - anything I can do for this?

All else works OK on the PC, Thunderbird was OK before.

Any way to back up my settings so I don't have to do all that again?

Attached is a sample of how web pages display. These can either initially display this way or, as in this example, the page opened correctly, I stepped away for a few minutes and when I viewed the page again it looked like the example. I can have a page open and it is displaying correctly, then open a new tab and go to a different site and the text will look like the example.

I have cleared the cache, dumped all the cookies. Restarting the browser (I do this many times a day) will fix the current page but eventually another page will display like this.

I running version 84.0.2 64bit on a Mac Pro Mojave. I don't have this problem with other browsers like Chrome or Safari. I never see it on my Windows 10 system.

Thunderbird 78.5.1 On computer A, probably since one of the latest updates TB is not able anymore to connect to the server, I only get the error message "connection to server xxx failed"

Activity manager shows no messages at all Server xxx is on my network, connection is not blocked TB profile seems to be ok : when using the same profile on computer B, everything is working fine

  • creating new account (same data as existing account) on new profile on computer A is not possible : message "Unable to log in at server. Probably wrong configuration, username or password"
  • however using exactly same procedure and data on computer B, it is working !

So, creating a new account on a new profile is not possible Disabling firewall and AV : no change TB safe mode : no change Reinstalling and uninstalling/installing TB again : no change Windows safe mode with Networking : no change TB config:security.tls settings are identical on computer A and B I changed TB config:security.tls settings : .version.min to 2, 1 and 0 : no change

and .enable_post_handshake_auth to true : no change
and .version.enable-deprecated = true : no change
(all after restarting TB)

Changing TB Server Security settings : no change

I deleted the stored passwords, but after restarting TB is NOT asking for the pw's meaning TB is even NOT trying to connect to the server ?

(error messages are translated from Dutch, so possibly not identical to English ones)

see also https://support.cdn.mozilla.net/en-US/questions/1304493 https://support.mozilla.org/en-US/questions/1269090?page=2 https://support.mozilla.org/nl/questions/1313268

I think I tried almost everything to solve the problem. It seems the problem is on the computer/TB installation, but where ? Can someone tell me how to proceed further ?

My Thunderbird updated today, and suddenly all of my emails are showing white text on black backgrounds, except for those incoming emails that have their own color schemes. In those cases, the text appears pretty dark against the black background. Changing themes doesn't seem to make a difference. Was there something in the update that made this happen? How do I fix it?

Ever since IE changed to tabs on top firefox coders followed like mindless automatons without any regard to/for Mozilla community and users. We are sick and tired of being ignored. We want/need tabs bellow address bar. Now, tell us how to simply get tabs below address bar or tell the coders to provide us with the option. And, we don’t care about any excuses as previously provided or outright ignored by them.

I'm getting Secure Connection Failed error on every single website I try to visit. Including sites such as microsoft.com, duckduckgo.com, google.com, etc. (Strangely, mozilla.org works fine.) Try Again never works, and Advanced - Accept risk works sometimes, but not always and if I close Firefox app and re-open it's back to the error page. I can't believe this is a common problem, so there must be something about my phone that's causing this. Android 11. Happens whether or not WiFi is enabled. What could it be?
