Hello,

After updating Thunderbird to version 153.0.1 ESR (64-bit), the InsertSignature button changed its position.

Before the update, the "Insert Signature" button was displayed near the message formatting toolbar, next to the "Body Text" selector.

After the update, the button moved to the top compose toolbar next to the Send button.

My environment:

- Thunderbird 153.0.1 ESR (64-bit) - Windows 11 - InsertSignature 0.4.5 - Quicktext 6.9.1

InsertSignature has not been updated recently (version 0.4.5), and this change appeared only after Thunderbird was updated.

The button used to be located immediately next to the "Body Text" selector in the formatting toolbar. Last Friday everything worked normally. Today (Monday) the button position changed.

Is this an intended UI change in Thunderbird 153, or is it a compatibility issue or bug?

If possible, is there any way to restore the button to its previous location near the formatting toolbar?

Thank you very much.

They will give you clear, tailored steps to try (like clearing specific cache files, turning off problematic add-ons/extensions, or resetting certain settings).

EVERY SINGLE TIME I try to access the 1Password extension it requires me to enter the Master Password for my 1Password extension. It never did before, if I entered it once I could use finger print access for a few day before it asks for my Master Password again. Do I have to remove the extension?

Hi, Apologies I've failed to find a more apt site to post this. The add-on/extension 'Remove Anything' was really useful. I have now discovered profiles and setting some up (they seem great), that and becoming a windows 11 user has caused me to have a hard look at the ones I installed. 1. 'Remove anything' has been great and I've been using it since late 2017 IIRC 2. The author ended support updates in June 2026 and updated the add-on page accordingly and pointed users to an alternative. I have to think this is best practice. We don't need many add-ons that do the same thing but kindly pointing users to a suitable alternative the author wasn't connected to was a helpful move. 3. I couldn't find a place channel to thank the author for their work but certainly appreciate it. 4. if anyone closing or casually reading sees this and could please pass on thanks from a typical domestic user to RoadrunnerWMC PLEASE Do. I greatly appreciate the volunteer efforts that created and run firefox and the big umbrella of related software, ever since the old Netscape days. That includes whoever is dealing this question. Good on you all! Best Wishes. Fiona J.

All bar one of my Extensions have stopped working on the last update (see attached image). I'm on Linux Mint latest, running TB 153.0esr. Also, I used to have two sent mail folders, one called "Sent" which showed all sent mail, and another called "Sent Mail" which was the useful one as it showed sent mail that hadn't been deleted. Now I have two called "Sent" which isn't helpful. Same with Spam.

Are there settings I can adjust to re-enable the extensions - the QuickText is the one I really need, and is it possible to rename the Sent and Spam folders as I can't see an option to do so.

I can not remove scenesource from settings and extensions, am doing this to reinstall because the scroll function is not working properly. Appreciate any tech help made easy to understand, I'm old, very old, LOL.

I have been using the browser extension feedbro and i really enjoyed being able to plop it out of the main browser window and 'add it to the taskbar' but for a couple days this option disappeared. Is there another way to do this? did "add tab to taskbar" get removed for browser extensions? or is this feedbro related? i am unsure how to test whether the button is missing for other browser extensions as well.

added two images showing that the button is gone from feedbro and still there for other tabs/pages

Can you please add the chrome extensions support in this mobile browser (focus browser). It's okay if not every extension is supported. What we want is support of unhook extension so that we can choose what we want to see in youtube. If you will add this fiture you will because my number one or two priority. I will start using your browser because I'm so frustrated by the shorts in youtube. And this is the only option to bypass that. And i think there are also multiple people out there who wants this same feature from you.
