I have been dealing with this issue for the last several thunderbird versions. I am currently running 115.18.0

Everytime I try to configure an existing gmail account for thunderbird via File -> New -> Existing email account

I specify my Name and gmail email address, then password for the gmail account.

The google authentication pop up launches " Mozilla Thunderbird wants to access you Gmail" and I click "Allow"

As soon as I click "Allow" I am asked to download a file.

Google gemini says this file is a sign that Oauth is not being accepted by thunderbird.

What I have tried. I verified Thunderbird is set to accept cookies I have verified there are no previously stored gmail passwords (as this has never worked) I have changed my default browser from Firefox to Brave and verified the same behavior

please help, Thunderbird has never been able to connect to gmail when running on this Ubtuntu install.

I have updated my firefox on W11 laptop to the latest version 147.0.3 (64-bit) but it cannot show any pictures from some, but not all, sites. Not from www.svt.se nor from www.yr.no But its ok from other sites, as www.tradera.com and www.kjell.com

It works fine using android firefox version 147.0.3

Any ideas, anyone?

Is there something changeable in Firefox that would allow things to display better? On Tue, Feb 3, 2026 at 11:27 AM Douglas Flegal <toemeister@hotmail.com> wrote:

Answer: Thanks for flagging this. We’re aware that some parts of the newsletter may not display correctly in Firefox, while they do load in other browsers. Unfortunately, this is a browser-specific issue and not something we’re able to control on our end.

Sometimes I want to enter arbitrary IPA strings into websites from my phone. I've tried finding a privacy-respecting way to conveniently do this and the best way I've found so far is to use the app Unicode Keyboard by Tim Wunderlich, available on the Google Play Store, and enter the code point for the IPA letters or diacritics I want. This works in every other app, but in Firefox, there are two characters I can't enter this way - the combining grave diacritic U+0300 and the combining acute diacritic U+0301. Even other combining diacritica work. I like researching and talking about linguistics and conlanging online, and sometimes this involves using those diacritics to mark tones. This is such an odd specific incapability for Firefox to have but it has persisted, since at least as far back as 2024. I've just had to enter those diacritics in another app and copy&paste them in. I can enter the diacritics directly as keyboard input in Firefox on Windows and GNU/Linux.

In the past week emails from one of my friends started going into junk mail. The person in in my contacts. I selected 'enable adaptive emailjunk mail..." and selected the correct address book. The mail still went to the junk folder. I changed the 'move new junk mail to: my inbox, still went into the junk folder. I had him send me 10 emails that I marked as 'not junk' still no success. My emails come from yahoo.com - went there and there was nothing in the spam or junk folder in my yahoo email account. This is happening to only one email address. There's nothing strange in the title of the email or the content. I've run out of ideas.

I don't know how to get to my prior question to update it I submitted a support question a short time ago about Firefox manage bookmarks using Waterfox version. I now think I could have been duped by the colour of the window bar. I have also found that firefox manage bookmarks does not show individual bookmarks that are not in folders - in the left pane. This also threw me. However, when I click on Bookmarks menu in left pane, the individual bookmarks are all shown in the RHS pane. I have done a quick check and the list does not contain at least two bookmark folders that are in my Waterfox bookmarks - I did not try to check all. I now think there is no problem. Interested whether anyone else has raised this. MY SUGGESTION - in the past I am confident that manage bookmarks function did not use waterfox color. In the next update try to change the manage bookmarks function window to a color different to Waterfox colors. This may not be possible if waterfox simply inherits the manage bookmarks function code incl colors.

Prior question text pasted here for completeness Yesterday I was using both Firefox and Waterfox. Since then when I try to use manage bookmarks in Firefox - I get the waterfox version of manage bookmarks showing the waterfox bookmarks list. Is there a way to get the firefox manage books back again

My computer suddenly started the above error message for multiple programs. The local computer shop was able to sort out what appeared to be the root cause and that recovered some things but I still needed to reinstall a number of programs.

The program I am terrified of reinstalling is Thunderbird. All my emails on five email accounts since 2011 are stored in TB and I naturally do not want to lose any of them.

The major problems are the computer is running Win7 Enterprise and I am 82 years old so I am prone to needing things spelt out in greater detail than many others.

Can anyone provide a way to reset the program permissions (preferable) or identify the best way to reinstall and still access all my historic emails?

Thank you

Hi, I have used "takeout" years before but not one of these.

Can I keep folder integrity using one of these? And how if not obvious.

Quota is high.

Thanks

When I go to another app, and back, tabs have to reload, often loosing what was done in the page. I have set Firefox as "No restrictions" on my Xiaomi 15 Ultra (HyperOS 3, Android 16), but Firefox still seems to unload memory very frequently.

My emails were all working (accounts were setup fine). Then, recently, when I opened Thunderbird, the main area (where my messages are displayed) is empty. If I choose another folder, still empty. BUT, the folders all say that there are messages in them (see the attached screenshot)

I have tried the following... 1. Opening Thunderbird in Troublshooting mode: This works, and the messages appear. But I don't want to have to open troubleshooting mode every time. 2. I have ZERO extensions installed, so asking to disable them obviously wont do anything. 3. I have tried to repair the folders (I have tried to repair the default inbox folder, and then tried to repair them all ... nothing worked). 4. I have backed up my thunderbird files, and tried reinstalling Thunderbird. Still didn't work. 5. I tried these three steps ... https://www.mboxtooutlook.org/blog/thunderbird-inbox-missing-emails.html Didn't work either.

Any other suggestions?

The last automatic browser update (147.0.3 (aarch64)) has wiped off all changes I made to bookmarks and passwords from the past year.

How can I go back to a previous version and recover my details?

This browser version is terrible and looks exactly like Microsoft Edge which is not intuitive at all. I don't want to set up multiple personas, Its just me and the one computer?

Please help me. Kerri

I have an existing account on my old computer. When I put Thunderbird on my new computer, it downloaded thousands of old emails but would not open new mail. I uninstalled and reinstalled and it still won't show new mail.
