Firefox Image Display Problem with Grok / xAI ChatI'm using:Dell computer Windows 10 Firefox (latest version)

Problem: Grok-generated images (graphs, memes, translated election charts, etc.) do not appear at all in the chat. I only see blank spaces or broken image icons. Right-click → "Open Image in New Tab" and Ctrl+Shift+R (hard refresh) do not work.This issue started during a long conversation where Grok was creating multiple JPG versions of an election results graph with translated text.Note: The same images load fine in other sessions/browsers, but I prefer to stay with Firefox. Is this a known compatibility issue with Grok's image rendering system in Firefox? Any settings, extensions, or workarounds (without switching to Chrome or Edge) that can fix it?

My Mozilla Firefox browser is not working. It does not open when I try to start it. I have restarted my computer, but the issue still persists. Please help me fix this problem.

Yes, I'd like to use the same account on both of my profiles.

I understand that for some users, this may be confusing.

In my case, the only reason for different profiles is that I need to use a Proxy Server for some websites, and no proxy for other websites. Manually switching proxy settings is painful, and doing so causes traffic for my other tabs/windows to go to the proxy, which I do not want.

I have a main (set of) windows (and its tabs) going straight to the internet, then I have a separate window (and its tabs) configured to go through a proxy (SOCKS5 in this case). I want all other settings, bookmarks, passwords, etc. to be identical to both. I end up having to logout of my main profile, log into the other profile to sync settings, log out of there, and log back into my main profile.

Is there a valid technical reason why an account on the same FireFox installation cannot be shared between two profiles?

I can do this on multiple computers (same account, different computers/profile), seems odd it is restricted to not allow on the same computer.

I have an alternative solution: Install FireFox natively, then install FireFox as AUR or FlatPak, but not sure this will collide as this both uses the same profile directory. Hum...

Hello- about 6 or 7 months ago I started noticing issues where I will type in a web address or a search term and it will not do anything after pressing enter. Just sit there blank. This does not happen all the time but is happening enough that it is frustrating. for example I could type in bank of america or amazon.com or something like that and it will not do anything. No spinning wheel no anything. I can delete what I typed in and try typing something else and the same thing. I can open a new window and try searching again and it will do the same thing. Then a few minutes later I can try it again and it will work fine. BUT what DOES work always is if I open a new private window and search that way it will always work.

Any thoughts? i've deleted cache/browser history, cookies, un-installed and re-installed. I have the firefox is up to date message. I am using FIrefox 151.0.3 64 bit Using windows 11 Home version 25H2

I use Google as my default search engine in firefox.

Thanks

Hello, I have six calendars: five are hosted by one provider, Runbox.com, via SabreDAV, and one is hosted by a different provider, Apple iCloud Calendar. I am periodically seeing the error shown below on multiple calendars during automatic sync.

I have saved a two-day event history from the error console and can provide it on request, along with any other troubleshooting information that may be helpful.

I am technical by nature, but my programming experience was primarily with mainframes rather than personal computers. Could someone kindly help me troubleshoot this ongoing issue?

Thanks in advance.

just let me know how i can get things in order. i am not an expert in these fields, for years you have been good and, fairly, simple. now it is all a pain in the neck!! how do i correct this?

the problem started 2 or 3 updates ago. I keep hoping the latest update will fix the problem. I can still access using Chrome. I've tried clearing cache and turning off ETP

I'm using firefox in ubuntu. A couple of minutes ago Firefox crashed. I restarted to a completely new Firefox. All my tabs, extensions, saved passwords, etc. were gone. This happened to me a few weeks ago. That time I found a solution: find a back-up of the old profile and manually restore it. I tried to reproduce that solution this time, only to find that there are no back-ups at all of my previous session. Is there a solution to this problem?

I cannot use Firefox without it blowing up my memory to 86GB used in Activity Monitor. I've cleared my cache, closed all my tabs and bookmarked them. I have a Macbook Air M1 2020. I've tried restarting and am definitely using the current version of Firefox. I also updated to the latest OS Tahoe 26.5 to see if that helped. What should I do next please?!

I wanted to use the Firefox browser VPN to check what the price of a certain Patreon subscription is in another country, but when the VPN is on, the website still correctly identifies my current location and shows me the price in my current country's currency. Is this a limitation of the VPN, or did I not set it up correctly?

I use eBird extensively. When I try to play the audio (with sonograms), I get a message that says "We are still processing this file. Try again later". These files perform well on my Android phone, so I know it it is not eBird's glitch. I am confused about the setting options on Firefox that I need to set. These files are usually .wav format. I have tried to open a ticket with eBird, but have not had a response. Can you guide me? Thanks.
