Firefox Community Forum

normally i just click the forefox icon on my taskbar and type claude.ai in the address field but today i was messaged that the claude program needed a mozila account - so I had to set one up. why and still cannot get to Claude

Most of the keyboard shortcuts are not working. Copy-paste works, but others for example, Ctrl + F doesn't work. Very confusing and frustrating. Attached is the screenshot of Browser Console and it does show missing attributes. Not sure if this is a browser issue (currently using 147.0.3 (64-bit)) or I need to make certain change settings. I would appreciate any suggestions to resolve this issue.

I’ve been troubleshooting a strange networking issue in Firefox that I haven’t been able to pin down, and it seems to be specific to Firefox’s network stack rather than my system or connection.

On several high-traffic sites that sit behind Cloudflare (Discord, Shopify storefronts, some SaaS dashboards), Firefox occasionally stalls during page load. The request shows up in the Network panel as pending for several seconds before finally completing. Sometimes the page partially renders and then hangs until the stalled requests finish.

A few things that make this confusing:

• The same sites load instantly in Chromium-based browsers on the same machine and network • The issue persists even in Firefox Troubleshoot Mode with extensions disabled • DNS over HTTPS on/off does not appear to change behavior • Packet captures show the TCP connection is established quickly, but some HTTP/2 streams appear to wait before data begins flowing • If I force HTTP/1.1 using a proxy for testing, the issue disappears

System details:

OS: Windows 11 Firefox: latest stable release Connection: fiber, low latency, no packet loss locally No system proxy configured

Things I’ve already tried:

• Clearing cache and site data • New Firefox profile • Disabling hardware acceleration • Testing with network.http.http2.enabled toggled • Comparing HAR logs with Chromium

One thing I noticed in the Firefox networking logs is that multiplexed streams sometimes wait behind earlier streams longer than expected, almost like there’s some internal prioritization or queue behavior happening. I’m wondering whether this could be related to HTTP/2 prioritization logic, connection coalescing, or how Firefox handles Cloudflare edge endpoints.

Has anyone seen similar behavior or knows whether there are any advanced networking prefs in about:config worth experimenting with (connection limits, HTTP/2 concurrency, etc.)?

Curious if this might be a known quirk with certain CDNs or just something unique to my environment.

I was looking for information (search engine Duck Duck-Go) about plants and suddenly I got a massage which says my iphone is hacked. I was not able to acrivate any button, besides the ok button, which I did not trigger of course. I tried to find info (pc) about the address but I shows a black screen. Than I removed firefox and re-installed it. Now the massage is gone. I have no idea where this massage comes from and if it will install malware if I would have used the ok button. It might happen again and it would be nice to know what to do Thanks in advance….

When I opened up Firefox this evening, websites stopped working if "DNS over HTTPS" is set to "Max Protection". In some instances, such as YouTube, the website loads, but it acts like you're offline and tells me to turn on my Wi-Fi even though it's already on and running fine. Weirdly, it seems that setting DNS over HTTPS to Max Protection, loading a website, set DNS over HTTPS to a lower setting, and then reloading the website fixes the issue, but it'd still be nice if we didn't have to go through the hassle at all. Thank you for your time and patience.

I HAVE FINISHED SET-UP BUT I AM STILL BEING PROMPTED TO FINISH, WHY FIREFOX IS MY DEFUALT BROWSER IHAVE IMPORTEDTED SETTINGS AND MY SYNC IS COMPLETE UNDER MY PROFILE

I just installed the latest version of Firefox. Now the reload button has gone from the toolbar.

When I click on customize toolbar it is not there either so I can't add it back.

Can someone please tell me how to get his back?

I've tried resetting and that didn't make a difference.

Firefox desktop saved logins not appearing on android. Sync enabled on both devices yesterday. Previously worked fine, kinda frustrating having to manually re enter everything.

Webgl has completly broken after last update for me. Forcing webgl in about config doesnt work and it doesnt work in troubleshoot mode either. Anything else i can try apart from reinstall from scratch as im worried about losing my history,saved account info and such. Or do i just need to do a full refresh and install? Thank you!
