Find out why and fix issue with pages not loading. Get a white blank page after a search inquiry on some web sites, (lowes.com),

Every time I launch Firefox, it attempts to connect to a number of domains automatically; some of which, it strikes me, may not be entirely necessary and should, therefore, not be automatic.

For instance, I have automatic extension/plugin updates off by default, so why does FF try to connect to versioncheck.addons.mozilla.org and/or versioncheck-bg.addons.mozilla.org every time I launch it?

How many of the following do I actually need to give a pass to in my firewall and how many can I safely block?

I appreciate that a couple (e.g. githubusercontent) may be related to specific extensions/plugins, but the majority are from Mozilla/Firefox, so what what is each of them for, specifically?

aus5.mozilla.org ciscobinary.openh264.org content-signature-2.cdn.mozilla.net example.org firefox.settings.services.mozilla.com ipv4only.arpa publicsuffix.org push.services.mozilla.com raw.githubusercontent.com redirector.gvt1.com services.addons.mozilla.org versioncheck.addons.mozilla.org versioncheck-bg.addons.mozilla.org

Thanks.

I'm trying to install Firefox on a Chromebook. I've done this successfully before. Using the instructions in the Mozilla page https://support.mozilla.org/en-US/kb/run-firefox-chromeos?utm_source=www.mozilla.org-firefox-browsers-chromebook&utm_medium=referral&utm_campaign=seo#w_installing-the-firefox-desktop-browser-with-flatpak

But the command in the terminal window sudo bash -c "$(curl -fsS https://raw.githubusercontent.com/mozilla/sumo-kb/main/run-firefox-chromeos/install-flatpak.sh)"

Is giving me the error message curl: (22) The requested URL returned error: 404

Any advice would be appreciated! This is a fresh ChromeOS environment since I just did a factory reset so everything should be clean, and with latest OS version.

Thanks

I wish to change the autofill of the email address when I log in to my yahoo email account . I think I need to get onto the ' Menu Panel ' but I don't know how to do this . Thanks

I have a lot a devices. I would like the majority of settings/etc to be synced with my account but I would also like to be able to have some add-ons excluded. For example I use Persepolis download manager for the devices that support it but not all my devices support it. Result is I have to toggle active addon every time I switch devices as it syncs.

Hello, I tried following methods online to disable private browsing however they don't seem to work (possibly due to being outdated?) and I was wondering if there is a way of disable private browsing in Ubuntu 22.04? I have added pictures to show what I implemented and it still allows private browsing.

Related to some personal SVG project files. Which are relative large files (containing lots of generated paths and other data).

On the largest of these files I spotted that some general svg-viewer failed with a "XML parse error: cannot load more than 200.000 XML elements" error message.

The same file, when viewed in Firefox (114~, Linux, Mint), also developed some odd hiccup that did not make sense. Unless ...

Is there a similar limitation active in Firefox ?

- I tried to see if "Inspect>Console" gave some potential related message on this. But spotted nothing out of the ordinary. - Searched developer.mozilla.org for any related svg data. But could not find any. - After ditching some data in the effected file, unrelated to the hiccup part, the hiccup disappeared. Suggesting I did hit some svg limit in Firefox. - File size: ~26.5MB. Number of elements: Other than more than 200.000, unknown at this point. (not sure how to count them at this moment either)

I've installed a new version of Ubuntu Linux and - as recommended on this page's FAQs - backed up my firefox profile, than copied it into the profile folder on the new os. Now Firefox tells me "You've launched an older version of firefox" and forces me to create a new profile :( Also loading the old profile in "about:profiles" leads to the same result

How can i restore at least my passwords? (When i try to copy only 4.db and logins.json from the old to the new profile, i get the same result)

I can't find an "import old profile"-function anywhere...

When I print to a PDF file, Firefox changes internal links (#go-there) to full external links (either https://the.website.tld/paper.html#go-there or file://home/me/paper.html#go-there).

This is obviously wrong, since the links are internal to the document.

How to I change this behavior?

Thanks.

Hi, I'm not sure if I just cant find the setting or if this is a feature request. I'm using the Firefox Developer edition, and I during web development I often deal with many query Params in the URL. Is there a way to have a long URL be displayed in multiple lines, or even better, one line per query parameter?

Best

I need to change my E-mail adress but cannot get into my Firefox account because they keep sending unlocking codes to my old adres that is no longer active. Please advise.

I was using Ubuntu before. I was using firefox and i had lots of recorded logins in that browser. I sign in with my current account and i opened sync including the password and login. Recently i changed my distro, i am using Fedora right now. I log in my firefox account, yet my passwords and logins didn't came back.

I was using Ctrl+K on some websites to do things like site-specific search, task bars, and so forth, but recently Firefox started capturing it for focusing on the search/address bar (https://support.mozilla.org/en-US/kb/keyboard-shortcuts-perform-firefox-tasks-quickly#w_search).

Is there a way to unbind `Ctrl+K` in Firefox?

Hi guys!

Sorry for dumb queston, just Iam not a web-dev) My problem is next: I need change default code page (charset) for every document. Its only one charset for all pages, so it can be hardcoded. Due no one another charset web-server do not use.

 Can you pls say how it can be realized? Should it be done by changing some settings files, or maybe need some code changes ( for example at intl/locale etc) ?

Regards, Ruslan

Currently Firefox is redirecting http://localhost:8080 to http://localhost:8081 , each time when type the address in the URL address bar.

I have been working with a container wordpress. I have tested in chrome the address http://localhost:8080 and all works fine.

How can we fix that problems, thanks in advance.

I have removed cookies and site data of localhost in Privacy-and-security> Manage-data>

Most of my bookmark folders are listed chronologically based on when they were added. One folder changed to alphabetical.... How do I change it back to the way it was for the order of the folder contents?

Hi,

Is there any reason firefox would flag an mp4 file legitimately?

• The file extension and file type are absolutely mp4.
• There seem to be no mp4 related zero days.

Does Firefox perhaps just treat all downloads from suspicious domains as malware? Is there a zero day I missed? Is this based on some missing metadata on the file or something?

Thanks for any advice you can give here, I'm scared.
