Firefox Support Forum

I use Firefox 82.0.2 (64-Bit) on Windows 10 and Foxit Reader 10.0.1.35811 for reading PDF files. In the FF settings I set the handling of PDF documents to "Open with Foxit Reader 10.0". Once I have done that and click on a PDF file I will be asked what to do with the PDF and I confirm again to open it with Foxit.

That usually works for the moment but FF will always forget this setting again. I have configured FF to use Foxit at least five times over the last days days. But the next day FF will just download the PDF file again and do nothing with it (not even ask me what to do with it).

Any help is much appreciated.

hello there and good evening:3 my husband and i are having this repetitive and extremely frequent bright yellow pop up with a robot that states "a webpage might be slowing down your browser." then the option to wait, or stop it. i've ran out of patience with this notification to the point to where even though i'de hate to, i would have no choice but to switch back to chrome just to stop being spammed by this pop up while im trying to relax. it happens more frequently on youtube and walmart.com, and i just want it to stop because it seems as if when it does show up, once it starts it never stops, and it actually slows down my webpage to the point of becoming unresponsive and stalling/crashing my only webpage open at the time. my husband has the same issue and we both use windows desktop. it only started appearing after the latest update. please, can someone help me make this thing go away? its very stressful and i cant browse in peace anymore on firefox. yes we have turned off all background processes, and we both have scowered settings troubleshooting for hours at a time to no avail, it just never stops and it behaving like a really bad bug.

The online store https://iherb.in.ua on opencart version 2.2.0.0 in Firefox does not display the table correctly, in chrome everything is fine, what could be the reason, please tell me.

Despite of countless plugins and efforts, My website Welding Zilla is still loading dead slow on firefox. I dont know whats wrong with it , while it is super fast with the other browsers. What can be the issue?

I hope someone can help me with this problem. I own the domain "cpaaffiliatesnetwork.com" and the site serves as my business site and access to my business network platform. The site is SSL secured and the SSL certificate was renewed in February 2021 for 1 year. Since the SSL renewal, I started having issues accessing the site from any browsers installed on this computer (Edge, Firefox & Chrome). I have now managed to fix the display issue in both Edge & Chrome through clearing cache / history, BUT, I have tried the same with FF with no success. I have also tried uninstalling and reinstalling Firefox, but, still receive the error below for any attempt to access the site: Secure Connection Failed

An error occurred during a connection to www.cpaaffiliatesnetwork.com. Peer’s Certificate has been revoked.

Error code: SEC_ERROR_REVOKED_CERTIFICATE

All external people i have asked to check the site have confirmed it works fine for them, but, it will not work for me. Hoping someone has a suggestion many thanks in advance :)

I'm trying to better understand why a certain website I frequent online seems broken or something with the level of tracking protection I have enabled with the main page working fine then the stories pages being spread out or something rather than what it was supposed to be like if this helps. I'm not able to read the story easily and have to scroll down over and over again and sometimes, the webpage won't allow me to go down on the page as well. I'm not too sure if that's because of the tracking protection level I have enabled and how to get around this if so rather than having to go back to the standard level. Feel free to share your thoughts sometime. Thank you in advance if you reply to this.

Firefox is downloaded and installed to my Microsoft PC. How do I make it my main browser? Or should I leave Google do the work and use Firefox occasionally? Also, how do I transfer or copy Google Bookmarks to Firefox?

We keep getting "Not responding" error that appears to be worsening - more frequently & longer duration. Happened at least 3 times since starting this submittal. Running Windows 10 with all current updates on Dell XPS w/ Core i7 8th gen. Have tried the fixes found online.

Thanks for your help.

how to increase and keep toolbar/bookmarks fonts sizes. I accessed the font sizes thru about:config. Then devp. Then layout.css.devPixelsPerPx. They keep reverting to the tiniest of fonts upon exit of browser.

I have version 86.0.1 running on a macbook pro. I followed the directions in the 'help' section and they do not apply to my version of firefox: Press the blue star, select bookmark and press delete. No such feature found. What can I do? Thank you.

Hi there

Due to the speed and unstable factors on your browser i have decided to cease usage from today. Already deleted the app from my devices. I can't believe how far you have dropped when once you were considered world leaders

Anyway by far better browsers out there, and I wish you luck. Should you improve, who knows maybe consider returning, but atm its just terrible

Goodbye and good luck

My ability to access PNC Online Banking has recently stopped working and receiving pop-up messages to try using another browser. I contacted PNC Tech Support and was told their system is optimized to use Google Chrome. Love my FireFox browser and do not want to download Google Chrome. Any suggestions as to locating and adjusting a setting to allow my FireFox to work with PNC Online Banking?

I have enabled HTTPS-only to everywhere.

Unfortunately I have a site that I need to use for work. The site is only available over a VPN, so security isn't a huge concern to the site operators.

The really unfortunately part is that the webserver seems to be poorly configured. So if I go to "https://dumb-work-url.com" then it resolves, but then just shows me a 404 error. I really need just vanilla "http://dumb-work-url.com" to work. As far as I can tell the override option that is on the padlock only works if I land on the functioning page.

I can disable HTTPS-only, and then go to the site, but then the padlock doesn't give me the option to disable HTTPS-only for just that website. I'd really rather keep HTTPS-only on all the time since I'll need to be visiting this site quite a bit.

I need a way to add this url to an HTTPS-only "off" exception list before I visit it. Is there a way to do that?

on the https site, I turned off HTTPS-only (under the padlock), but that setting either isn't working, or isn't applying to the http version.

Whenever I click the Firefox browser icon, it will start up, and then close a second later. I have tried reinstalling the program, yet this doesn’t fix the problem. I saw a crash report the last time that it worked and ignored it. Is there a way to bring it back up? I tried to do it myself while running it as an administrator, but that didn’t work either.

3 days ago I tried to log in to my email account. A very long string of letters, numbers and signs appeared and blocked my entry into my email. Here's that string:

https://redir.peridot.synacor.com/?to=zmail&u_d=bowens63.q.com%40embarqmail.com&sid=af86ad64dc420c66302c015c5f637215&zmuser=bowens63%40q.com

How can I delete this to gain entry into my email?

Thank you!

When copying an image from another program, such as Snagit or powerpoint into gmail using firefox, I get two identical copies of the image.

When copying formatted text from Powerpoint to gmail, the text also shows up twice -- once with the formatting, and once without the special formatting.

However, when copying text from Word to gmail, the text only shows up once -- with the formatting.

This does not happen with Chrome.

It does not happen when copying the image or text into another microsoft program like word. It only happens in Firefox.

I have refreshed Firefox, disabled add-ins, and cleared cache. Nothing helps.

Please advise on how to stop this from happening when copying an image or formatted text.

This problem has only started in the last couple of weeks. I am using Firefox Version 87.0 Build ID 20210318103112

with Windows 10.
