Hello Thunderbird team,

First of all, thank you for the great work on Thunderbird for Android. I've been following the community discussions and noticed that many users are reporting recurring issues related to email syncing, notifications, account setup, search functionality, and overall app performance.

As a suggestion, it might be worthwhile to collaborate with experienced mobile app development companies such as AppVerticals. Their expertise in Android application development and user experience could help enhance performance, improve stability, and address some of the common issues users are facing.

I'm not affiliated with AppVerticals—I simply believe that bringing in additional expertise or consulting with companies that specialise in mobile app development could benefit the Thunderbird Android project and improve the experience for the growing user base.

What do other community members think? Would collaboration with external mobile development experts be something worth considering?

Thank you for your time, and I look forward to hearing everyone's thoughts.

If you'd like, I can also Make it sound more community-driven, technical, or feature-request focused.

In Windows 10, FIREFOX is preventing the proper operation of the Windows 10 feature called MOUSE KEYS when FIREFOX is operating. MOUSE KEYS is a very important capability to individuals with certain disabilities.

MOUSE KEYS enables the use of the numbered keys on the NUMERIC KEYPAD to be used to move the cursor around when the NUM LOCK key is turned ON, as a substitute for using a mouse. Does Mozilla have a way to prevent FIREFOX from defeating this MOUSE KEYS feature?

Google AI indicated that there is a solution specifically for FIREFOX. That capability is built into FIREFOX and begins by using "about:config" to reset a parameter named "permissions.default.shortcuts" from either "0" or "1" to "2". I successfully implemented the steps in this solution by changing that value from its default value of "0" in my computer system, to "2", but no change resulted. MOUSE KEYS continued to malfunction in the same way.

After exhaustive testing looking for a pattern, I finally found one. The malfunction appears to be the following: With the MOUSE KEYS feature activated in the WINDOWS 10 set up, and with NUM LOCK turned ON to assure that this function is ON, each of the numeric keys, 0 through 9 on the keypad, cycles through the different MOUSE KEYS functions of all ten of these keys, in ascending order by their number. For example, if you press key 7 for ten times in a row, it will cycle through each of the ten MOUSE KEYS functions associated with the keys 0-9 to occur, returning on the tenth press to the function that was executed the first time that key 7 was pressed, and so one endlessly through multiple cycles. And similarly for each of the other ten numbered keys.

A similar type of malfunction of MOUSE KEYS occurs with any BROWSER program that I have tried, including GOOGLE CHROME and BRAVE. I gather from GOOGLE AI that browser programs INTERCEPT the codes generated by the numeric keys on the numeric key pad and change those codes before sending the codes to the WINDOWS 10 operating system, and thus to MOUSE KEYS, for execution, causing this problem.

Is there a solution for FIREFOX what will restore the proper function of the MOUSE KEYS feature of Windows 10, when FIREFOX is being used? Thank you for any help that you can provide.

Since Firefox does not support video calls, deaf people cannot chat with their friends in sign language on Facebook Messenger. This feature should be brought back.

I can't listen to a YouTube video when I open a new tab. Also the video stops. When I use my android power button to close screen. I was able to do this both these things on my old Samsung ao3 phone. Now on my Samsung a16 I can not

Hello, I'm a user who's blind, of course as per the accessability topic I selected here. I need help with thunderbyrd and reaching back to the messages list from either a message body and/or now currently, from the settings pane. I've tried the following: 1. Hitting F6 to figure out where the message list lies within the cycle of panes, but all I get are the search pane and the reading pane main region. 2. Tried hitting tab from the spaces menu when I find the mail as alt 1. 3. Just going back into that tab, the mail, and nothing works. I still end up back in the settings currently but was in a message body before. No matter how I turn off thunderbyrd and reopen it, this is still happening. I use NVDA only for games/current screen reader in use, but I mainly use JAWS for Windows, which is on its latest updates. NVDA is as well. Is there anything you can suggest or should I just use the outlook new from Microsoft, which I still have but it's a pain to use with screen readers. Thanks soo much, Ashleigh P

Each time navigating to settings>Accessibility in order to adjust the zooming for the current page is frustrating.

Add a menu option that controls Zoom per Site just like most browsers.

Here's a clear and concise version you can send to the Mozilla Firefox team:

Firefox for Android does not work properly with Android screen readers. When browsing websites, many accessibility elements such as checkboxes, combo boxes, edit fields, buttons, and other controls are not announced or navigated correctly. This makes web browsing very difficult for blind and low-vision users. The same websites work much better with Google Chrome and Android Accessibility services. Please investigate and improve Firefox's accessibility support for Android screen reader users.

High contrast setting only support 2 colors(unvisited links and visited links) as a consequence it does not support radio buttons(switches that move to left and right to turn on features). the buttons are invisible and waste hours of the users time.

Display Problem: Each time I sign-in the - User ID field and Password field are white boxes, and the text I type is also white (invisible) on a white background, them fie;d are working but the text color is wrong . Please help me unmasking this problem to become visible (normally) again. Thank you.

Hello, I am using fire fox on a Nothing phone 4a Pro. Recently the page formatting has changed on YouTube. It wasn't originally like this... As you can see in the photos, when browsing through a channels videos it has them organized in a weird manner to where I cannot read video titles... The YouTube homepage has also changed. I think my app updated and then it automatically formatted YouTube this way. Firefox YouTube on my Samsung and iPhone are not having this problem.

On the sides and bottom of most content screens in FireFox there are Scroll bars to help navigate the content. In recent updates those bars have been made so narrow that it requires extreme dexterity to keep the mouse on them while scrolling and are impossible for someone with a tremor issue.

Is it possible to return them to a normal width? Maybe this should be an Accessibility Option.

Hello developers.

I really enjoyed using Firefox on iOS. It is so much better than other browsers in terms of continuity. However, I do find that there’s one particular thing that Firefox can do better—how to access bookmarks.

“Bookmarks” on the Homepage should be able to be put on top. On the current version, the location of “Bookmarks” is fixed on the bottom of the screen, below “Shortcuts” and “Jump back in”. For many users, including myself, bookmarks are more convenient than Shortcuts. It would be great to move it up top.

And it should be able to show folders. I have a lot of bookmarks, so I have to group them in several folders. What current version does is probably guessing which specific one you want to pick and show it, and the hierarchy is dismissed. So maybe it should show it exactly how it is on the desktop.

That’s all suggestions I got. Thank you for your reading.
