Firefox Community Forum

Hello Mozilla Support, I am getting Error 526 when I try to open YouTube in Firefox. Other websites work normally, but YouTube does not open. I have already checked my internet connection and restarted Firefox, but the problem still exists. Please help me fix this issue.

The new Pop Up in Firefox that asks me to choose how to open the link I want tosend to share with a relative, or a friend is driving me crazy. I'm 82 years old, I'm legally blind now and this new POP UP has to be disabled or eliminated somehow. I've searched instructions on YouTube and triedd under Privacy & Security, Permissions and disabled PopUps BUT The new Pop Up in Firefox is till functioning. Please may I give you permissiontoremove it in my account!!!! Please could you do thatforme because I'vetried every suggesion ad I can'tseemto disableit or removeit. THank you for thekind attention you are giving to this matter, I do appreciateit. Sincerelyy, Patricia Haring [redacted] @gmail.com [redacted] @panix.com [redacted] - please call me if you require any furtherinfo or permission. Thank you so much!

Hi Mozilla Support Community,

I use Firefox Desktop as my primary browser for running a corporate consultancy agency. Recently, I've noticed an issue with Firefox's built-in PDF reader (pdf.js) on certain official interactive forms.

When downloading, previewing, and filling out business registration forms, MOA templates, or tax certificates from corporate web portals (such as the SECP Portal Pakistan for company name search and FBR verification tools), certain custom font fields in the PDF appear overlapped or fail to display input text properly.

System Details:

Firefox Version: Latest Desktop Release (Windows 11) Issue: Form text fields in interactive PDFs fail to render non-standard font glyphs properly. I wanted to ask:

Is there a specific preference in about:config to force Firefox's PDF.js viewer to fallback to system fonts for interactive form fields? Is there a way to reset pdf.js rendering cache without clearing general site cookies and sessions for web applications? Any troubleshooting tips or about:config tweaks would be greatly appreciated. Thanks! https://secpportal.com.pk/

Running on Windows 11. There are many supposed "solutions" on the Web, but none of them work. I have tried with: about:config, css files, etc. None of them work.

I like Firefox greatly, but this is so frustrating.

The developers have created a solution to a problem that didn't exist. The result is to make Firefox user clumsy.

It would have been nice if they - at the very least - had provided a way to change the 'Profiles' icon position on the menu.

Again, Firefox 153.0.1 (64-bit) on up-to-date Windows 11. Amd Ryzen 5, 6 core processor, 32 GB Ram, 500 GB SSD C drive = 197 GB free.

I'm running Firefox 153.1 64-bit on Windows 11 Pro 25H2. I have a LOT of bookmarks. Possibly over 3,000. Somehow over time I've managed to create a LOT of bookmarks in the Other Bookmarks folder unintentionally. I need to move and merge those to the correct Bookmarks Menu and ideally eliminate any dupes. Everywhere I look for a process to accomplish this I seem to get a lot of "can't be done". Does anyone know how to do this? Thanks for any help.

Until a few months ago, I was able to turn off the underlining of URLs in web pages that I create. But within the last few months, all URLs appear as underlined, even in documents where they had NOT been underlined a few months ago. I am using the text-decoration setting to control this aspect. Look at page https://www.w3schools.com/CSS/tryit.asp?filename=trycss_link2 in the Edge browser, and see the "This link changes text-decoration" change between underlined and not as the cursor is moved on and off of that sentence in the middle box. Now look at the above page in latest Firefox. Moving the cursor on and off of the "This link changes text-decoration" sentence causes NO change to that sentence -- it always is underlined.

I refer to the w3schools.com website when I wish to learn about a new-to-me feature, and I have found their site to be accurate in the past.

you have to delete over 5 times to get history and cookies to clear. Selecting "everything" never removes everything :( Used to be the best for privacy now its seemingly deceptive..

Dozens of reboots every day due to video seizures only with Firefox. Tab crashes causes those I am ordered to support to LOSE WORK. After a tab crash and restore the FF interface is frozen -- no type of input from peripherals possible. This is all supposed to be solved by Monday. If I am out of luck with FF -- just tell me. That's very simple. New machines, new OS and it's worse than under the legacy systems we support after moving up from Win 7 Pro.
