Greetings,

Today, I went to access my Bookmarks, & found them "Empty", other wise "Missing"!

I found the "How to recover missing Bookmarks" topics, & that did bring back,what I consider to be My "Permanent Books", bu the section called "Other Bookmarks" will not come back, no matter how many times I go through the "Restore Bookmarks".

I Absolutely need that section to be restored, for I had many files in that section that I updated daily, that I planned to move to the "Bookmarks Section".

How can I get get this section restored?

Firefox can't load some websites but other browsers can in Windows 10 (version 20H2)

Dear Community,

I have problem with my Firefox version 86.0 (64-bit). I have Windows 10 20H2 64-bit operating system. Firefox can't load some websites. For example I can load https://allegro.pl/ but I have problem sometimes with this website: https://allegro.pl/myaccount/newpayments_incoming.php

If you go there and use F5 key on keyboard (refresh website) sometimes this can't load. On other browser I don't have this issue. This very frustrated me because I can't work. On Windows 10 1909 on older machine (another computer) I don't have this issue with my firefox (this sam 86.0 version). So this is probably problem only with Windows 10 20H2.


Steps to reproduce:

1) Open new tab and go here: https://allegro.pl/myaccount/newpayments_incoming.php 2) Log in to your account for Allegro website (without account you can't load website) 3) When website loads normally you must refresh this website (F5 key on keyboard) few times (you must be patient, sometimes this can take some time) 4) When website can't load or it's load partly you can see that this stops loading when it try connect to analytics.google.com so I think that it is very strange behavior.

On other browsers on Windows 10 20H2 version this website works without issue. Only with Firefox I have a problem. On Windows 10 1909 version on another machine I can't notice this issue. Also on Ubuntu I don't have any problems with this website with firefox.

Can you fix it? I can't work on my computer with Windows 10 20H2 system. I musted to switch to another browsers (Google Chrome, Microsoft Edge). I contacted with owner of the website but this is not the first problem with Firefox on Windows 10 20H2 so you should fix it. I remember that I had some similar problems on another websites but I don't remember what was address for these websites.

Actual results:

Sometimes I can't load this website on Windows 10 20H2 64-bit: https://allegro.pl/myaccount/newpayments_incoming.php

When website can't load or it's load in a part you can see in the bottom of the browser that this stops when it try connect to analytics.google.com so it is very strange behavior.

This can be not problem only with this website.

Expected results:

I should load this website always: https://allegro.pl/myaccount/newpayments_incoming.php


I hope that you can fix it.

I save many items and documents as PDF files using the Microsoft Print to PDF option, rather than physically printing on my printer. This worked fine for quite some time. This option no longer works when I am using Firefox, but it still works if I use Chrome.

I would rather not have to switch to Chrome whenever I want to print something to a PDF file.

How can I resolve this?

My Firefox (version 56) on Ubuntu 18.04 suddenly stopped working. The program starts, I can access menus etc and type an address, but nothing renders at all. I have no issues with other browsers (Chrome, Chromium, Konqueror) or other internet applications. The firefox issue is also present for other user accounts. The issue is both with internet sites and sites on my local network, such as my router.

I have tried:

  • Booting in an older Linux kernel
  • using IP numbers (that work in other browsers) instead of DNS names
  • Firefox safe mode / refresh
  • Deleting profile completely
  • Completely purge Firefox (and mozilla profile directories) and reinstall (versions 56, 67, 86) both from canonical and from mozilla.org
  • Updating Nvidia graphics driver from v415 to v460
  • I was able to access the config and preferences pages by specifying it from the command line (firefox about:config or firefox about:preferences) so I could try:
  • Checking proxy settings (no proxy)
  • disabling IPv6

To no avail. All versions of Firefox remains just white. I'm out of ideas - any suggestions? :-)

The only thing that did work was this "portable" firefox: https://www.orbital-apps.com/blog/2017/firefox-quantum-now-available-as-a-portable-app-for-linux


Cheers, Esben

Hello, im a web developer and have come accross a problem which only occurs in the firefox browser.

When i design a website, i use the www version of it always, and have redircts for all other instances, eg; mydomain.co.uk > https://www.mydomain.co.uk http://www.mydomain.co.uk > https://www.mydomain.co.uk https://mydomain.co.uk > https://www.mydomain.co.uk

So they all end up at the secure www version of the website. This is done in the .htaccess file and works great in Chrome, Edge, Explorer etc just not firefox.

In firefox i get the error

Warning: Potential Security Risk Ahead

Firefox detected a potential security threat and did not continue to boothandco.com. If you visit this site, attackers could try to steal information like your passwords, emails, or credit card details.

What can you do about it?

The issue is most likely with the web site, and there is nothing you can do to resolve it. You can notify the web site’s administrator about the problem.

Ignoring it then procceeds to the full https://www. but that warning screen will be enough to put potential visitors off no doubt.

Is there an "easy fix" for this or is the only way to solve the problem to use up more SAN's and double up on www and non-www versions of each website?

Any help is greatly appreciated.

Thanks Chris

Why do nightly updates lead to a change in my default Search Engine? After every update, all my searches (address bar and search bar) are done via the default search engine (Yahoo). I do not want this. For the 5th time I have changed it to my preferred site. The OneClick search preference is not changed - and here the Default Search Enginge is not even selected as an option.

Any help would be appreciated.

On my Mac Book Air 2015 there is no About Firefox in the Help Tab. So I can't see a current version of Firefox and other features from About Firefox. Also some addons are not working properly (Spoof Timezone for example) and I think that there is some connection between these issues.

Hi, I've an old printer, a HP 970Cxi which I think is similar to a HP 970cse. I've used firefox for a long time with this printer with no problem, but recently it started printing double width or more characters rendering the printouts useless. If a document is in PDF form, I have to save it and then print it out from a separate PDF viewer. If printing a web page or a receipt, I have to use another browser or try and copy the page to MSWord for printing. I'm guessing this might be a problem caused by an update, but if not, what setting is causing this? The paper is set to A4 and all settings I can see look fine. Thanks

Firefox opens and has a teeny tiny little address bar and tabs and everything else displays differently. I've tried making Firefox my default browser. I've tried updating twice. I've tried combing through preferences for anything that might make a difference.

Nothing works. In the picture, for reference, the Apple and menu bar at the very top are normal sized.

I'm gonna be honest, this is the LAST time I'm giving Firefox a chance. If I can fix this relatively simply, I'll do it. If it involves me needing to suddenly know how to be a software engineer and go into an obscure file in an obscure folder of an application and mess with anything that ends in .css, I'm out.
