When I switched to vertical tabs in Firefox, the Hikcentral professional web client camera server page changed, part of the page appeared at the top, making it difficult to use and watch the camera images, and the image doesn't display properly. How can I fix this problem?

When v143 was released something happened to the shortcuts row(s). Regardless of refreshing efforts, rolling back versions, and searching the forums, there's no way to consistently get the shortcuts back. Sometimes they appear with a new browser instance, sometimes they don't. They don't appear with new tabs, and they don't stay when they do appear with a new browser. Grrrr. Please restore the shortcuts!

Dear Team,

I am currently facing an issue with Thunderbird, and it has not been resolved yet. Therefore, I am unable to send emails through Thunderbird for the time being.

Until the issue is sorted out, I will be sending emails through an alternative method.

Thank you for your understanding.

While browsing on my desktop , I am unable to open E Shram Card blog. it appears like there is an error in connection , but despite of good connection, cannot open it.

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.

This just happened, (45 minutes). When I attempt to access a page or a file, when the page comes up on screen, it is a page of numbers and symbols. How do I remove these pages??

I updated firefox through apt, and since then, have not been able to log into twitch I am on ubuntu 24

apt list --installed | grep firefox firefox/mozilla,now 144.0.2~build1 amd64 [installed]

Attempting to log in returns the generic "Your browser is not currently supported"

Hyperlinks keep opening in new windows, not in the same/existing window where they were selected. Issue is not unique to Google Search results and occurring across multiple websites. At wits end trying to figure this one out. I have deselected the "Open links in tabs instead of new windows", turned off all extensions, and uninstalled & reinstalled Firefox. Issue is still occurring. Attached is image of my tab selections showing all turned off.

I have accessed the particular website many times but today it says, "Hmm. We’re having trouble finding that site.

We can’t connect to the server at shop.naturalcompounder.com.

If you entered the right address, you can:

   Try again later
   Check your network connection
   Check that Firefox has permission to access the web (you might be connected but behind a firewall)"

I can't open Firefox at all, so I downloaded Firefox again, before I got your message. The Crash ID: ⁨bp-958359b9-d3d4-4cba-aa19-4dcbc0260313⁩

That is the only one, not five crash ID's. I couldn't open Firefox to find an omni.ja file.

I can't import or access my bookmarks or passwords on the new Firefox I installed. Would you please be able to help with that?

I'm suddenly having a problem where images don't save as .jpg unless I add that myself. At first, it wanted to save images as WebP, but I was able to fix that in the about:config. Now when I go to save an image, it wants to save as Chrome HTML document and I have to click all files and then add .jpg.

Hi everyone,

I do a lot of downloading images in bulk for my neocities website and its really helpful for me to be bale to drag an image from say, tumblr, to my neocities tab and just drop it into the download box. I love Firefox but I couldn't find a way to use this feature, so I downloaded the QuickDrag WE extension, which allows me to drag and drop images from duckduckgo images, but not tumblr.

(for info I'm using Windows 11)

Would love to have some help on this! Thank you Kit
