Firefox Community Forum

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.

frustrated and thinking about moving away from firefox. why not let us choose whether to update or not??

cookies deleting you have to search for each and everyone (why not sorted by installed date???) then one has to delete all the site cookies that are ok cause such a big effort to clear cookies!

no longer able to bank cause bank changed their cross site settings and firefox wont let me through...have to watch the status in bottom left corner and hope I can read it fast enough.

laptop always behaves like cell phone...can't read, can't see desktop properly

I've been using Firefox for 25+ years, always keeping it up to date. I've been a customer of CIBC Bank for 20+ years and using their online website since its beginning. Last week I've been unable to login to my accounts without going thru an inconvenient and time-consuming telephone code procedure every time. Previously, this procedure had been in place only occasionally as a secondary method of identification.

CIBC advised changing my anti-tracking and cookie settings. After trying all the alternatives, there was no change. Checked out Edge browser, and it was the same. Checked out Firefox and Edge on a second computer and it was the same. Installed the Chrome browser, and it works fine!

No problems accessing any other website. Anyone ever experienced this? Any suggestions?

On my main laptop I built a nice homepage with shortcuts that I use regularly. I would like this exact homepage on all the devices where I sign in with my Firefox account. Instead, every time I sign into a new device and sync, my homepage is completely destroyed and scrambled on all devices, including my main laptop and I have to painstakingly recreate the homepage I want. What is going wrong here? How can I set up one homepage on one device that will be synced to all other devices?

I am suddenly receiving virus notifications from videomart.org. I have tried numerous settings but I am unable to remove it from Firefox. Do you have a fix Thank you

Hello, when I click on link with middle mouse button it will open that link on next tab but doesn't "jump" there, which is fine. But when I do the same with pdf links, it will automaticly "jumps" on the pfd file. And I don't want to. I want to open it like normal link (on next tab in background), because I have a lot of pdf files to open, and this makes it difficult to do it qucikly. Before some weeks this wasn't a probem, it started now.

Bes Regard, Josef

Hello!

I have had this problem for about 9 months. The reason is somehow related to the autoplay of multimedia on web pages. Technical information is given at the end.

After starting work on the computer, all functions work correctly. The video plays normally. After several hours of working at the computer, scrolling through the feed on Instagram (before the video appears in the feed), or viewing stories, or opening a video on YouTube, the web page freezes for a few seconds, after which the screen also turns off for a few seconds (not goes blank), and when it is turned back on, the video either does not play at all showing the loading animation, or only the sound is played, and instead of the video, only a rectangle filled with a random color (black, green, pink) appears.

After that, ALL videos in ALL open tabs stop playing again. Google spreadsheets also stop working (sometimes it also happens because of them, not the video).

This issue also affects other programs on this PC. For example, Telegram Desktop. It shows previews of images and videos, stickers and GIFs, but when I try to open an image to full screen or play a video, the screen goes completely black. But at this time the video is playing and I can hear the sound. Although the mouse cursor is not showing, the controls work and I can close the view in the upper right corner.

Restarting programs does not solve the problem, but ending the Windows session or restarting helps.

OS: Windows 10 Pro 64-bit (21H2) Firefox: 103.0.1 64-bit currently, problems started since 80s version Hardware: Intel Core i3-7100 CPU @ 3.90GHz; RAM 8Gb; Intel HD Graphics 630

What has already been done:

 - disabling all add-ons
 - memory test using memtest
 - complete reinstallation of windows with formatting of the system disk

How can I gather logs or technical information about these crashes to find the cause?

PS. Sorry for the mistakes in the text. this is google translate

I use Firefox on multiple devices with synch. I don't want Firefox to ask to save logins, never ever anywhere. :) On my laptop, the option is greyed out and checked, i.e. set to ask to save passwords. So this settings syncs to the other PC's. When running about:config and looking at the option there, it is set to true and also here set to true without possibility to change.

Clues? :)

For years I am able to click on different emails and view my messages. But suddenly the one email (see screen shot) is not syncing. I don't know if this is a Firefox issue or AT&T. I have tried everything I know but the problem persists. AT&T tells me I should not be able to see multiple email addresses but I have been doing it for years. Does anyone has a solution to this problem? I am using the latest app from Currently,AT&T/Yahoo!+. AT&T just does not care about this. If you can reach them, they can't help. It is driving me crazy.

Good Afternoon,

Yesterday I went to use my Arkscan Label printer as I always have for years and it distorts the image very largely as appose to fitting 4 x 6 as it always has. I re downloaded the driver, checked my setting from my label shipping site (etsy) and all is the same. My co-workers is still working, (she does not do automatic updates). After reaching out to technical support from Arkscan it is a widespread problem after your latest update to firefox. I was suggested to use a different browser such as Chrome or Edge. Will you be addressing this issue ASAP or should I use another browser from here on out?

Thank you,

Hey guys,

try to open the https://web.whatsapp.com/ whilst the history settings are on Never Remember History - you won't be able to do it.

The page will not download and you will see just the empty page.

Is there any workaround, or makeshift?

Best, Salaidin

Hi, I am Sign-in the application through Iframe. then I am open the Same Url in new tab which I used In the Iframe. But It does not read Session and local storage. Please help me to resolve the Issue

Background; Yesterday I had corrupted file in Windows 10. Windows 10 wouldn't open and the solution was to reinstall Windows but save my data but lose the apps. When I reinstalled Firefox, all of my book marks were gone.

I have gone to the support articles provided and pulled and tried to locate my "old" profile. I couldn't my last attempt was to go the Profiles Manager ( about Profiles). I see the Profile default and I see the Profile default release. I have switched between the two and neither are My Old Profile.

The question: I want to be sure I have exhausted all possibilities in locating my Old Profile, before i start the manual rebuild process?

Also I have by data backed up in Carbonite, but I don't know if is backed up there or how to find it.

Thanks in advance for any help or suggestions.
