Whenever I change my VPN (not Mozilla VPN) status, Firefox will refuse to connect for something like 30 seconds then times out, leaving me with a blank screen. I have wait until that interval has passed before I can retry, otherwise it will repeat the freeze. This happens whenever I turn my VPN on/off or switch to a different VPN server. It happens only with Firefox. Chrome and my email client have no problems whatsoever. I think it's some kind of DNS caching problem within Firefox as the problem doesn't happen if I visit a site that I hadn't visited very recently. There's immediate response if I do that. I have DNS over HTTPS and secure DNS turned off in the settings, so it can't be those.

Anyone else have this problem? I wish there was some way to clear Firefox's DNS cache other than having to go into about:networking

Is there any way to select other than the "home" calendar as standard? Have tried to change order in the calendar setting, but when I accept a meeting invitation it always place the meeting in the home calendar. I would like to select the syncronized Google calendar.

The syncronization with Google calender works perfect when manual enter something.

While this is a Privacy and Security setting issue - at least tangentially - my question isn't about security so much as how this data is being stored/retrieved.

I navigated to an entirely new site the other day and it requested a username and password. When the cursor was in the Username field, a set of proposed entries showed up. These were all (recognizable) first names - not emails. When I checked the Privacy and Security settings, I couldn't find any of the names in stored data. While this may be just cached entries for similar fields ("username" or "name" etc...), the list I saw was heavily curated. One of the names I don't ever recall even entering in any name field (and wouldn't have been used for any login) - but even if I had, the list that I saw was far from exhaustive and would only have been a very specific subset of any data I would have entered into any "name" or "username" field.

Is there somewhere I can find how that list was generated?

Thank you,

I have two computers, one older with TB 115.9.0 32 bit, pop. The other has 115.9.0 64 bit, imap, same email address. I have tried to merge them, but when i do the Thunderbird Import folder has zero messages and no subfolders. I also tried changing the old TB to IMAP, didnt work: "configuration problem". Any help would be appreciated.

I had a few issues with Hotmail and Firefox in the past as described in other posts. Now it has stepped up a gear. I can use the internet for anything, but the moment I open my Hotmail account in Firefox my Lan card stops working. At first I had no idea it was Hotmail, I tried everything from switching cables to using wifi only. When it happened on wifi I realised every time I went into Hotmail on Firefox my network card stopped functioning and I had to restart the computer. The thing is, when I use Hotmail through Microsoft Edge nothing happens and all is well with the world!!! No network card shutdown. I could read between the lines but I'm no conspiracy theorist, however, I don't think the problem is with Firefox. Is there any solution? I don't use Edge and I don't want to start.

Whenever i sign into youtube and then close the window when i come back ive been signed out and have to sign in again. i have "delete cookies and site data when firefox is closed" off and dont know what else to do

Hello everyone, a long time ago i changed my youtube name to something else and to this day it never updated on firefox. Yesterday i finally asked youtube support about it and they told me to check with mobile or other browsers and there it works fine, so only firefox is borking out on that one. Do you have an idea how i can solve that?

sincerly, Cammy

I want to export mails only of a certain mail account (I have got 6). I would like not to export ALL accounts in ONE zip file but I want to have different zips. Is that possible? Why do I want that? I am active in 3 different organisations and I have a private account and - it can almost not be avoided - a google mail account. So when I look for a certain mail I know which zip I have to import and to look for it. Years ago I used MS outlook and I had the possibility to create archives as defined for each account and - if necessary and wanted - for each year. Is this also possible in Thunderbird? If yes HOW? Many thanks in advance!

I have attached images of what slowly occurs when I don't clear my cookies, websites start to slowly and slowly load less and less until they eventually completely break and wont load and I have to clear my cookies, resign into everything. and rinse and repeat every few days or a week, I also attached an image of what the purchase screen is supposed to look like. Looking at this via Microsoft edge

hi guys, i want to change my default favicons but i cant find this path on my mac.

.bookmark-item {

 list-style-image: url("chrome://global/skin/icons/defaultFavicon.svg");

Dear Sir or Madam,

I have been having problems with Firefox on my Desktop-PC for about a week now: I am almost always shown another tab with an error message (an new tab with allways the same content) in addition to the website that is regularly called up and also works:

Tab-Headline: Seiten-Ladefehler Fehler: Verbindung fehlgeschlagen

Beim Verbinden mit 0.0.0.1 trat ein Fehler auf.

   Die Website könnte vorübergehend nicht erreichbar sein, versuchen Sie es bitte später nochmals.
   Wenn Sie auch keine andere Website aufrufen können, überprüfen Sie bitte die Netzwerk-/Internetverbindung.
   Wenn Ihr Computer oder Netzwerk von einer Firewall oder einem Proxy geschützt wird, stellen Sie bitte sicher, dass Firefox auf das Internet zugreifen darf.

It doesn't matter which regular website I call up - it also happens when I call up the Mozilla Firefox page.

It is as if my website call is executed twice: once normally and everything is displayed correctly. And once as an extra tab with an alleged page loading error where the connection has failed.

How can I prevent these additional tabs with the error message from constantly popping up and being displayed? I have not made any other settings and Firefox has always worked perfectly so far. It doesn't happen with Google Chrome, for example - so it's not my PC.

Can you help me?

Kind regards Daniela Bohle

I use the Rapport Add-on to protect my personal info especially when doing on-line banking at the moment I have to use Chrome but I would rather stay with Firefox but you dont have this extension why?

I want to use the Advanced Preferences (about:config) to select 'Manual proxy configuration' setting. I have been able to set the HTTP Proxy and associated port but I am unable to find the setting in Advanced Preferences that will select Manual proxy configuration. Could someone please help. Thanks

I keep getting this message that pops up in a private window to restart to keep using firefox. Everytime I click restart Firefox, it closes my tabs and opens them again. However, 5 minutes later the window pops up again. Even after repeated attempts of updating, even doing a full restart on the computer, Firefox continues to send this window to me. The private window in the bar says about:restartrequired.

I've tried uninstalling Firefox with a fresh install as well as doing a Refresh of Firefox. Neither seem to solve this problem.

Firefox is not permitting videos from YouTube that other browsers easily play. This needs to be fixed. YouTube offers their Premium subscribers videos which can be played at a higher bitrate, which means even 1080p can play at a higher quality. When setting quality on a video, in addition to the 1080p, you can choose "1080p Advanced bitrate" as an option. Firefox has trouble playing these files, whereas Safari and other browsers don't have a problem with YouTube. Please fix this.

Here in Jan 2024 suddenly TB will no longer connect to any hotmail or outlook..it says I have to enter a new password but I have not changed my password and can get onto them if I go directly to that site. Any suggestions?
