Firefox Community Forum

Hello, since the recent update, firefox tabs' font look different. Like blurry, doubled. You see the picture. It was not like that til like some minutes ago before it got updated.

I tried accessing Canon printer help files and got a message that Firefox was not supported.

I later tried downloading a manual for a BAOFENG UV82 ham radio and it would not do it.

Neither problem showed up when I tried with Windows edge.

Isn't this somehow illegal?

I usefirefox because it's modular taking this away means I walk so just let me force already got a browser that doesn't give me lip when I try to head weird cites from eastern europe

Just in the past few days, Firefox is useless. Cannot access pages. I have not made any changes. Whatever you changed in Firefox screwed everything up. Links give error message. Your links give the same error. I've had to switch to MS Edge do do anything on my computer. Firefox blocked my online banking. Firefox blocked my VOIP phone app. Firefox is keeping me from opening emails.

Hello,

Firefox used to provide a way to remove the: "This connection is not secure." warning message for sites that are using "http". Believe me, I understand the need for security, but when the site is an internal, intranet site behind a firewall, why is there no longer a provision to turn this warning message off? This makes no sense to me. I have no problem with the "Not Secure" indicator up near the URL. That makes sense. Chrome does this, but they don't assume every "http" site is most likely dangerous. Again, I'm talking about "http" sites that are internal, intranet sites that can only be used by people inside their firewall.

Thank you, -Joe Hummer

Hi!

Ever since the release of version 157 and above my browser crashes almost immediately after startup. Downgrading to 156 does not crash. I have the same problem on my desktop AND laptop.

I have tried to:

• run without any extensions.
• a complete reinstall
• create a "new" profile.

After doing that and logging in to my firefox account to sync bookmarks and passwords it starts to crash again after a day or two.

I'm now assuming something is "corrupt" in my cloud profile, is there any way to reset that one while keeping my bookmarks/passwords?

Or does anyone have any idea what can be the problem.

I have the exact same problem discussed in this previous thread, and the fixes didn't work for me either. https://support.mozilla.org/en-US/questions/1268375

I have to delete cookies before i can get https://vip.idaholottery.com/ to load every single time I go there, even 2 minutes after I get it to load the first time. My Firefox is up to date. It just started happening a month or so ago.

Summary While Gemini Deep Research was researching a topic and building a PDF report, Firefox's memory and CPU use shot up and the whole laptop became sluggish. System RAM reached 12 of 13 GB. It came back to normal on its own after the report finished.

What I did 1. Opened gemini.google.com in Firefox. 2. Asked Gemini to research a topic and create a PDF (Deep Research). 3. While the report was being generated, the system slowed down badly.

What I measured - Firefox held about **2.6 GB of GPU (GTT) memory**, which comes out of system RAM on an integrated GPU, and it ran at about **100% CPU**. - Total GPU GTT memory in use reached **5.3 to 6.7 GB**, while normal process memory (RSS) added up to only about 5.4 GB. - System RAM reached about **12 of 13 GB in use**, and the system started swapping. - After the report finished, GTT use dropped to about **0.2 GB** and free RAM went back to about 3.8 GB. - Measured from `/sys/class/drm/card1/device/mem_info_gtt_used` and `drm-memory-gtt` in `/proc/<pid>/fdinfo`.

System - Laptop: Lenovo V15 G4 ABP - CPU/GPU: AMD Ryzen 7 7730U with integrated Radeon graphics (2 GB reserved as VRAM, 16 GB RAM in total) - OS: Ubuntu 26.04.1 LTS, kernel 7.0.0-43, GNOME 50.1 on Wayland - Browser: Firefox 159.0.1 (Flatpak)

Questions 1. Is this expected for Deep Research, or is it a known issue? 2. Is there a setting or workaround (for example turning off hardware acceleration, or switching away from the tab while it generates) that reduces memory use? 3. Has anyone seen the same thing in Chrome, or on other integrated GPUs?

Thanks!

I'm currently in macos 15.8.2 that was the start of the issue. Till a few weeks ago I could print to samba mounts without issue in Firefox. Currently nothing gets saved(no requests for permissions if that was an issue, no errors). I have 5 other browsers on this machine, all can save pdf prints without issue. I have been jumping between browsers and moving PDFs printed on my local device for a week.

How can Firefox print PDF files to desired destination? Firefox updates after 14 October 2026 no longer produce PDF files. The interface goes through the motions, but going to the save locations shows they're not there. Looked into the Downloads folder, and did a search on my computer, including attached hard drive. Additional actions performed:

1. Installed Adobe Acrobat Pro DC to replace Acrobat X Pro. 2. Checked Firefox settings and preferences. 3. Cleared Firefox cache. 4. Restared computer.

Logging in to Yahoo thru Mozilla, I was advised that password was incorrect. I don't know why, same password I have used forever. I tried changing using the three voices option, was OK, but it recycles again asking for the same info. I've changed password, I think, in Mozilla, but I don't know how this affects Yahoo where I get my emails. I've created a passkey, but don't know how to activate or if I should. Help!!

The pdf creation/save tool is no longer working to create or save document as pdf file to computer. The browser does go through the motions resulting a "file" name to download and save but nothing happens.
