Have tried suggestions from other strings. Will not open in any mode on my Mac mini so cannot even uninstall. Continue to get message that It is trying to install a new helper tool but will not install or open. Restart did not work, shut down and restart did not work, “safe mode” with shift key or option key does not work.

After Update 128.8.1esr installed on 3/19.2025, I cannot receive or send messages. Worked fine in the morning on 3/19 and after update I get nothing. I have an AOL account for my email. I can get my email by going through the AOL internet site, but nothing through Thunderbird. The previous update was 128.8.0esr installed on 3/7/2025, and that worked fine.

Hello, Any help would be tremendously appreciated! Can someone please tell me very briefly the steps to switch from the FF 128.8 ESR version to the latest supported regular version, which I believe is FF 136. From my research, it appears that you can download the regular version and go to about:profiles to switch your profile back to your original one used w the ESR version. Please list the very simple steps (1,2,3 etc) to switch from ESR to regular version for a non techie.

My background, I have an older MacBook Pro mid 2015, which had 10.11 installed (El Capitan) and recently took the plunge & updated to Mac OS Monterey (12.7.6), which was the highest allowed for this older MacBook. The new OS is awesome & fixed so many websites that were no longer working.

Firefox automatically moved me to the ESR version at some point with my older Mac 10.11 OS. I believe my latest supported version was 78.15 ESR. When I recently updated my MacBook OS to Monterey 12.7.6, Firefox updated automatically to 128.8 ESR.

Now, many websites recently seem to be broken (gmail, yahoo calendar, duckduckgo, & others), so moving from ESR to the most recent regular version seems like the best solution (I believe FF 136 is highest supported by Mac OS 12.7.6). Please list the very simple switch steps or point me to an article. Thanks very very much.

I just installed Thunderbird and it opened with the Welcome to Thunderbird (donation request) page.

BUT I can't DO anything in the app like setup an email address or access settings because the hamburger menu button does nothing when I click it. I can't click anything that will let me actually do anything. It's essentially a brick out of the box.

Could my antivirus or firewall perhaps be interfering with it? Seems unlikely since the problem is within the app itself and not a connectivity issue but I can't think of anything else and there aren't support articles on this fundamental problem.

I'm running Windows 11 with all updates. I tried restarting the app but no change. Any idea what's going on and how to fix it? Thanks.

I have installed Thunderbird on a new Lenovo PC using the latest version of Windows. I have copied the settings manually and correctly from a laptop in to the settings for the accounts on the PC. Thunderbird does not give any errors for collection of email though none are appearing in the inbox. There are messages on the server waiting to be collected.

There is a timeout on the SMTP when trying to send messages so no messages are sent.

I have checked all the settings and they are as follows: POP account port 110 smtp port 587 Using START and normal password authentication for both.

I have tried numerous other permutations of configurations as well as restarting Thunderbird after every change. As I mention these are the identical settings used on the laptops which the PC's are replacing. The PC is connected to the internet via ethernet cable and the internet functions fine.

Any ideas out there or anyone having had a similar experience and found a resolution?

Hello.

This most recent update of the Firefox app for Android has suddenly made it so that all of my bookmarks and bookmark folders are out of order. The desktop version does not have this same problem, and syncing between the desktop and mobile accounts does not seem to fix anything.

Another issue I noticed with regards to bookmarks on mobile is that where once I could pull down while in the bookmarks tab to 'refresh' the sync, this feature suddenly does not work either.

I have done 4 total clean re-installs of the app and signed back into my account each time. The app then works as normal, with no bookmarks/sync/refresh issues. Within the next day, however, the app restarts itself and the bookmarks are scrambled again with no sync refresh operating.

I have tooled around the support forums and seen that at least since Ver. 133 other people have had this same issue. The support forums are really not user intuitive and I do not know where to go to have an actual conversation with the developers instead of hoping someone responds to a thread if they feel like it.

I really enjoy using Firefox as my default browser, and have never had this issue before on mobile after any app update until now. If the developers could please take the time to look into this request and work out a solution that doesn't include re-installing the mobile app every other day, I and many others would be very appreciative.

Running TB 136 on my new Macbook, I transfer my old profile from TB running 128, I use IMAP. The first thing that I noted was emails in my Drafts, Sent, and Spam folders did not transfer, and the Template Folder is missing. I did the transfer by moving a copy of my TB profile to the new install. How do I get the missing emails and the Template folder?

Thanks! Charles

One of the things I love abt Firefox Focus is its simple Google search page that won't show any trending topics and it really makes it a no fuss browser.

But after the recent update in android 136.0.1 , I am utterly disappointed that the thing I loved the most abt this browser is no longer there and Google search looks just like it looks in the chromium based broswers.

I want developers to consider this request to make it look like before, it would really make this actually a No fuss browser.
