Firefox just started, seemingly unprompted, replacing - > (without the space) with U+2192. Just visually, however, as moving the cursor left from the end of -> puts it between - and >. This only occurs in Firefox fields such as the url search bar, settings search, Ctrl+F search, and the fields in this form. All other forms unrelated to Firefox as a product or company seem to function as expected.

For unknown reasons I cannot load ATT mail or Myatt. I have turned off virus protection and adblock, same result. Not sure when this started. Windows 11 Home. Dell XPS desktop, i9,

IME toggle not working in youtube chat on Firefox, even in troubleshoot mode. It works in all other applications including Chrome browser yet I prefer using Firefox so hope issue can be solved.

Need to have my selected bookmarks in sidebar at all times...since update have to do it every time i open...want it to be permanent without constantly having to do it via selecting view etc

This is making multiple "WARNING"s to appear. I believe that it is causing my DELL to shut down arbitrarily. How do I delete this ?

Hello Firefox Community,

I'm experiencing a strange issue with my website, https://www.hostgrap.com.

When I visit the site using Firefox, I get the following error:

Bad gateway Error code 502 Visit cloudflare.com for more information. 2025-05-14 04:02:47 UTC

Browser: Working Cloudflare: Working Host: Error

However, the same website works perfectly fine on other browsers like Chrome, Edge, and Safari.

Troubleshooting steps I’ve tried in Firefox:

Cleared cache and cookies Disabled all extensions Cleared DNS and HTTP cache via about:networking Checked proxy settings (set to system default) Tried Private Window Flushed system DNS Updated Firefox to the latest version

None of the above resolved the issue. The error appears consistently only in Firefox. I’m using Cloudflare for DNS and reverse proxy, and the server is working as expected for all other users/browsers.

Additional Info:

OS: Windows 10 Home Single Language Firefox Version: 138.0.3

This issue happens even after disabling all add-ons

No custom rules in Cloudflare specifically targeting Firefox or its user agent

Is there something Firefox-specific that could be triggering this behavior with Cloudflare or my server?

Thanks in advance!

I work for the Gwinn Area Community Schools, and this is my work computer. (As in, it has never been used for anything 'adult') I searched the term "call" in the search bar, and one of my suggestions was a little dicey. Yelp suggested, "call girl in Gwinn, MI" I just wanted to make sure you guys were aware, in case there are more edge cases like this that could be a lot worse. I would like to continue supporting Mozilla's funding initiatives, but I'm going to have to turn off sponsored suggestions if I get results worse than this.

I just made this Mozilla account to file this, so I was not signed in when this happened. I have searched call very frequently, as I am often adding students to our "call down" list. Not sure if the frequency would have had an impact. Happy to answer any other questions if needed!

Again, I don't think this one's a huge deal, but definitely something to keep an eye on! Thank you for all your work on the hands down best browser!!

I've recently sync'd my PC bookmarks etc to my android tablet and since then web sites that previously remembered me now keeping asking me to log in. BBC news, FaceBook are examples.

When I enter the verification code I received over email, it says "Bad request: Something went wrong. Please close this tab and try again."

There's no bad requests in the Network tab under web developer tools.

The virtual keyboard on my HP OMNI 10 tablet has begun popping up at every touch of Firefox. This makes it almost impossible to use. Expected/normal behaviour is that when you touch web pages or any app., the keyboard stays out of the way while you move around. When you touch inside a textbox, the keyboard should pop up so you can type. Touch outside the textbox and the keyboard drops down. Now, ( since the start of May 2025 or so, I think), the keyboard pops up every time I touch the Firefox page, anywhere. This makes it almost impossible to use.

For example, on a Youtube video, I touch the video to start playing.... and the keyboard pops up, covering up the video! I have to touch the x to drop the keyboard down again. When I want to rewind or move forward, I touch the video to get the controls to appear and...the keyboard pops up, covering the video. I have to touch the x to drop the keyboard and by then the video controls have timed out and gone away again!

Right now, if I close the keyboard and touch this page outside the textbox, the keyboard pops up.

In Microsoft Edge the behaviour is normal and in an app., like Notepad, the keyboard only pops up if I touch inside Notepad.

By the way, I did all this typing once already but when you said you couldn't read my troubleshooting information automatically, I tried your manual steps, and that took me to another web page. When I came back to this page, all my typing was gone! Very annoying. please don't do that again.

Version: Firefox 138.0.3 (64-bit) on Ubuntu 24.04.

When browsing, the tabs and address bar get stuck somehow. Tabs can still be closed with "close other tabs", and new tabs can be opened by following URLs, but the tab component is fully stuck. Sometimes it fixes itself, but usually it requires browser restart.

hi, the latest update seems to have removed the entire drop down bar from ebay, (copare 2nd atatched image to first, under username etc) to get this to work i am having to go through edge browser, can you please provide a working sulotion? 1st image from firefox (missing the entire navigation bar) and 2nd from edge. i hae disabled ublock and restard browser etc but the error persists.

I have no problem with previous version of ff. i noticed ask to save password not showing up in this version. usually if i fill in a form, ff will save the information for future use.

i have issue with ff, so i uninstall and reinstall. doesnt work. i add additional information in notepad attachment.

i am end user. nothing technical. only uses ublock, clearurl and audio equaliser. not heavy user. just light browsing facebook, google and regular website.

No doubt I had something to do with the (fancy font uppercase in bold) B appearing in my Firefox header line as the first and left-most character (image attached). Anyone know the source for this and how to shut it and anything else it does off? I like many others I have read commenting about unwanted things thru the PC years that have a disdain of things that sneak through uninvited.

The other thing so far as I know had nothing to do with Mozilla or Firefox but I'll mention it in case someone has an idea. A product install by the same name permanently labeled an outboard drive with this label bold text'Roboform2Gobold text. I know how it got there, it was with the install the product by that name, which I uninstalled, and no one from that company would or couldn't tell me how to get rid of the relabeling it had done. Uninstalling the software didn't take it out, and no one in a general forum had any suggestions. I know the traditional approach of adding or changing a label, but change attempts don't affect this reminder of a poor product that I had decided not to keep. They refunded, but did not help with the changeless drive label.
