Hi, Im having trouble getting access to my add-ons menus. There are no icons for add-ons in top right corner. After installing an extension it seems gone to background, inaccessible.

why is there no back button on thunderbird? I clicked on a message (have to click twice on it now in the lousy upgrade I was forced to use), and now I can't go back to the inbox. What's up????

Like all of us, I get bombarded with spam emails. So I set up filters to separate the "definitely spam" from "possibly spam". I've been doing this for many years now. But recently, maybe for the past few months, I'm finding that these blacklist filters aren't working anymore. The filtering failure seems to be getting worse as time goes on. And, yes, I do a match on "any", but that still doesn't work. As I said above, my filtering rules used to work just fine, but possibly a new Thunderbird update several months ago broke filtering?

Also, is there a way for filtering on the message content URL? I find that sometimes that's the only way to distinguish spam.

I added my own shortcuts and deleted all the preset ones (Wikipedia, Twitter, Amazon etc). On deleting the last one of the default ones, the 'Add a shortcut' button has completely disappeared. Is there another way to create a shortcut?

This is a follow-on to https://support.mozilla.org/en-US/questions/1401783, I have the same problem - I've followed https://support.mozilla.org/en-US/kb/extended-add-support (which is for some bizarre reason marked "no longer maintained"), to create the custom collection https://addons.mozilla.org/en-US/firefox/collections/17515772/raxod502/ so that I can override the arbitrary blocking of third-party extensions that Mozilla applies by default.

This allows me to install most extensions but for some reason https://addons.mozilla.org/en-US/firefox/addon/duochrome/ is not showing up in the interface on Firefox for Android, despite being in the custom collection. No information is given about why it is not showing up. I am not aware of any reason why it would be blocked. Here's the manifest.json: https://github.com/FreshSupaSulley/Duochrome/blob/main/firefox/manifest.json

How can I fix this and use whatever extensions I want to use, or at least get a valid error message about why Mozilla is blocking the extension?

Creating a new thread since the older one just says "Even using that approach, not all add-ons are supported in Firefox for Android at the present time", which doesn't help at all - there is no reason why any addon should be blocked for mobile usage unless it is explicitly configured as such, and even if that were reasonable, it doesn't help explain what specifically is wrong with the extension I'm trying to install.

I would like to know what the options below, contained in the settings editor, are for and how I can adjust them so that every message sent is configured to require confirmation of receipt by default:

mail.identity.default.request_receipt_header_type mail.identity.default.request_return_receipt_on mail.incorporate.return_receipt mail.receipt.request_header_type mail.receipt.request_return_receipt_on mail.request.return_receipt mail.server.default.incorporate_return_receipt

Is there a way to set a separate theme for the private browsing option? I like being able to visually distinguish between the normal browser and the private one, but enabling a theme seems to set the same visuals for both.

If separate themes are not a thing, perhaps they could be added in a later update?

Thanks for all your time and effort.

Hello, I use Duck Duck Go as a default search engine, with Google and others as alternatives. Since I switched my compter, Firefox resets the default engine back to ebay, which cannot be deleted in the list and also shows up in the address bar. Could you please tell me how to get rid of it? Thank you very much!

I have a fresh install of Debian 12.5, which came with Firefox 115.7.0esr. Firefox is inconsistent in following the settings I put in. For example, I specified the download folder, but it still automatically saved to the original default folder. But when I clicked to ask me before downloading, it does! And it gives me the 1st option to save the the folder I specified. But if I uncheck the "ask me" button, it goes back to putting downloads in my home directory, which I don't want. Another example is I've set it to "open previous windows and tabs on startup", but it doesn't. When I close Firefox with several tabs open, the next time I start it I have just the home tab. Yet when I look in "settings" it still says it's supposed to be opening my previous tabs. This is more annoying than the download issue. How can I get Firefox to follow the settings, which ARE being saved?

Hi, I am experiencing an issue with desaturated icons in the toolbar and tabs of Firefox. I don't think any extesion may be causing this problem and i have already tried reinstalling and resetting Firefox, but this did not resolve the problem.

why everytime i use firefox the default web address is: https://hao.360.com/?src=lm&ls=n077c1cd59a

For many years I have used the ability to set shortcuts to website on the Firefox home tab, using the method given at: https://support.mozilla.org/en-US/kb/customize-items-on-firefox-new-tab-page#w_pin-unpin-or-remove-a-shortcut.

However, today, when I try to edit a shortcut link, I do not get the 3 dots menu by right clicking on a shortcut tile.

Is this a recent change, a bug, an issue with my installation (which has been stable for many years)?

How can I get back the functionality back?

I am using Firefox 127.0 (64 bit) on Windows (Windows 11, all up to date).

I have stayed on an old version of TB because of the old extensions that made it a much better product.

With the installation of Win 11 I decided to try the latest version of TB. I have to say I am not impressed. I forgot how much better TB was with the extensions.

My first question is how do I get to sort the order of items I see in TB? I want News & Feeds to be displayed above my email accounts. It would seem that this would be easy but I cannot find a way of doing it. What am I not understanding? Surely this should be simple? I want to choose the order of everything.

I also customised the interface with better scrollbars etc. None of the add-ons I used to use seem to work with the latest TB. At the moment the new install of TB is incredibily ugly. How do I change that?

I added a PNG picture as a background to my emails. Instead of a single background picture, it produces a collage (can't think of another word) of multiple copies of the same picture. Any way to just get a single picture?

I use the Mozilla Thunderbird email program and have just been overwhelmed by the number of "bookmarks" appearing under the "Bookmarks Toolbar." I don't want these additional bookmarks that I did NOT select. Moving them one by one is tedious--and I think new bookmarks are added to the toolbar if I delete any. How do I stop this? Is there a way to eliminate the added bookmarks in mass rather than singly? Thanks,

Hello,

I've recently uploaded a custom-made extension to the Chrome Web Store for my personal use and for a few specific users. It's currently awaiting review.

However, I'm encountering an issue where I cannot download and use the extension myself. When attempting to download, I receive the message "Download failed. Please check your connection."

Although I can see the extension listed on the store (since it's mine), I'm unable to use it personally.

Could you please assist me with resolving this issue?

Thank you.

I found my old password Firefox recovery key after I already changed my password and got a new recovery key. Can I use my old recovery key to get back all the things (eg bookmarks) that may have gone missing with the switch to a new password?
