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- I've followed https://support.mozilla.org/en-US/kb/extended-add-support (which is for some bizarre reason marked "no longer maintained"), to create the custom collection https://addons.mozilla.org/en-US/firefox/collections/17515772/raxod502/ so that I can override the arbitrary blocking of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.

For the last few days Firefox keeps dropping off as the default browser and seems to be defaulting to the Avast Secure Browser thats installed instead.

I keep changing it back via both Firefoxs settings and via Windows default settings but within 10 minutes it falls off again.

How can I make sure Firefox stays as my default browser?

Picture in Picture is an awesome feature and i love that Firefox comes with it by default.

However I do wish for one thing. So we can lock and "click through" the picture in picture, instead of our mice being able to click it by mistake when doing other things (such as grinding on an MMO or something.)

Is there any way to get these options in the near future? It'd be great to play some games when watching a video during slow times! Thank you!

Right now i love my HDR content in most scenarios, except on a few sites where its just bad. Is it possible to be able to block it on certain sites where you dont want to apply it?

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?

Im currently reading books (pdfs) in firefox and I would like to hide the scroll bar. Im using full screen mode and especially the bar the the bottom is annoying while reading. I've seen a few topics posted about this issue but they are from a few years back and the solution posted doesn't seem to work anymore. (creating profile/chrome/userChrome.css with some code) But maybe the code is just outdated or I did something wrong. Im not too sure.

The best solution to me would be to just hide the bottom scroll bar. I didnt find any option in about:config except for making them (bottom and right) both thinner.

I would greatly appreciate any help.

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.

I can not get thunderbird to stop opening a web page on start up. Deselect the "when thunderbird launches......." but it is turned back on once I close and restart

It actually opens my browser and opens a thunderbird donation page.....

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