• OS: Debian (trixie)
• Firefox version: 149.0b3

Firefox suddenly crashes without any displayed error. Attempt to troubleshoot it in "safe mode" doesn't help (it also suddenly crashes.

• When I had redirected following output: "Exiting due to channel error."
• after restart, I launched "about:crashes", but there were no entries

For over a year, my browser occasionally loses connectivity. It may work for 3 hours or 3 days, but inevitably new tabs will stop working and then slowly the others will stop as well. When this happens, none of my other browsers are impacted. They work fine. It is only Firefox. The only solution is to close everything and lose all my work.

Once I do that and restart Firefox, I receive an error message telling me I am using an older version of Firefox that is not compatible with my profile. The only solution that brings me back to the best starting place is to re-install Firefox.

My company IT spent 3 days trying to find the problem and couldn't. I have uninstalled and reinstalled so many times. All extensions are turned off, as are the two add-ons. I have been using Firefox for over a decade and prefer it to all other browsers, but I need to find a solution or I am going to have to move on. Help!!!

i go to chrome have no problem getting and keeping Facebook i have closed and enable the extensions removed some and it either does not work or takes for ever in the version of Facebook. . I keep checking if Facebook is down there are limited problems but i do not see the problems in Chrome. if this keeps up i will be going to chrome which i really do not want to

What are the step-to-step instructions in order to use Free VPN? (see attached image) I did a query on the web and it came back stating that Firefox VPN was not free. I am confused. Thank you for your prompt assistance.

Hi,

I updated to Firefox 149 (German User) and did not get the Seutp prompt mentioned in https://support.mozilla.org/en-US/kb/built-in-vpn#w_turn-on-vpn-in-firefox I Also tried https://support.mozilla.org/en-US/kb/built-in-vpn#w_how-do-i-turn-off-or-remove-vpn-from-my-toolbar to check the Optiions in the Settings, but there is also the part "VPN" missing. In the Help Section it says that I have installed 149.0 (64-Bit) Windows Version. Is there something missing?

best regards

Best Buy Tech support took control of my computer today to get my printer to scan to the computer. After that was done, I went to my FIREFOX hompage only to see it completely changed from the way it was and I am now trying to get it back.

I'm not sure what happened. I restarted my laptop and when I tried jumping onto Firefox it didn't have my normal accounts on it they were gone and I had to make a new one which means all of my bookmarks are gone, none of my accounts are logged in I am freaking out! What happened?!?!

I don't have VPN option in the toolbar settings, there's no settings featuring VPN, I didn't see VPN setup prompt. I have Split View tho. What do I do? Is built-in VPN not available in my country (I'm Russian)?

• OS Version: Microsoft Windows 10 Professional (x64) Version 22H2 (build 19045.6466) • Firefox 149.0 (64-bit) • Thunderbird 140.8.1esr (64-bit)

Have NO idea "which topic best describes my question" from your drop-down list (above), so simply clicked on one.

Restarted my PC; all of my bookmarks disappeared. NOT acceptable. (Or is this just another "improvement" from Firefox . . . ?)

Where did they go; how do I retrieve them?

Really don't want to wait days until there's a response, as I DO USE MY BOOKMARKS ALL OF THE TIME.

Thank you.

Since the update to Firefox a few days ago, I am no longer able to view PDFs in the browser. They still open, but they show up as blank pages. Is there a way to fix this or to revert back to the previous version of FF?

Thanks.

I am trying to activate the new free VPN feature, however your steps are not matching what's on my screen.

The first step from your [Set up VPN] article says:

"Look for the VPN setup prompt in the top-right corner of your Firefox toolbar.

   Click Next to begin the setup process. "

Yet I am not receiving this prompt.

I have logged into my account, encountered issues with my authenticator app and back up keys not being saved, and so signed up with a new mozilla account using my secondary google email. (This account I am raising this ticket with now. My primary account/email is [edited email from public] @gmail.com).

Hoping you can clarify or give an easy route into activating this wonderful new service you've announced. Am I right in understanding that it is different (ie. built-in and free?) to your Paid Service ?

websites are being blocked when I click on links from my email account and I don't know why but I also want it stopped the websites are Stage32.com and https://course.fp-platform.online/learn/hRpTYcFi2UyZKzLm2gaOHg/theory

This what you said: "Today we’re introducing a free built-in VPN in Firefox, a new IP-protection feature designed to keep you even more private while you browse. We’re starting by offering an industry-leading 50 gigabytes of free VPN-browsing each month." But all I see are the paid options. I want to try before I (might) buy. After all, you constantly preach that we have to be careful & trying to be careful.

my firefox is up to date (version 149) but I don't have the icon VPN on my toolbar

how can I implement the new VPN (free) in my firefox?

thank you for your help

Sometimes I need to open XML files on my PC or in a network folder. If I open the file in the first tab in Firefox, it displays a neat and formatted rendering that makes it easier to read. However, if I open yet another tab, it displays a sequential text file that's difficult to read. How can I apply the style of the first tab to all open tabs? I've attached explanatory images (I hope). The second image shows how I'd like the XML file to always be displayed, regardless of the tab's position. Firefox 149.0.2 on windows 11
