Diễn đàn hỗ trợ Firefox

After having upgraded my W11 system to 25H2, I cannot install any extension. Installation terminates with "... something may be broken". I'm using FF 144.0,2. FF is used in more than one account alternatively.

On a second system, with less security measures, I have no problems.

hello - since yesterday, the links on the startpage don't show anymore, even though they were perfectly fine the day before yesterday, when I shut down the laptop.

i can't find where I could change anything, since in the settings, the 4 lines are still activated, nothing has changed except they're suddenly not showing anymore.... ?

what can I do???

I did try to search through the articles, didn't see anything that could help me.

I would even save them and open a new profile if there's no way to fix it, if only I could find where those links on the startpage are stored...

thanks for helping.

On my previous laptop using Windows 11, a dialog box would open when I entered a username and password while online, asking if I wanted to save the username and password. On my brand new laptop, that dialog box does not come on screen. Id like to be able to store that info so I don't have to enter it each time.

Thanks!

Hello!

I use a VPN when I access the web and I recently updated my OS (Mac OS Tahoe). I updated Firefox and now DNS over HTTPS (DoH) is enabled in Firefox. When I have my VPN enabled, I cannot access the web, there is some problem with DNS resolution. I have changed my Firefox DoH settings to Standard (I have also used Strict) and have typically been unable to resolve web URLs correctly. There have been a few times that I have been able to use 'Standard' DoH strictness / settings and also use the VPN successfully at the same time, but typically when I have the VPN enabled Firefox cannot access whichever 'mozilla.cloudflare' address it is attempting to use for DNS resolution.

The VPN vendor suggested always using the VPN's DNS resolver. I have done this and I still have the same problem. What should I do to ensure that I have secure DNS and can successfully use a VPN?

Thank you.

Hello, I reset my PC yesterday.

I didn't know my Firefox password anymore and clicked "Forgot password."

Then I created a new one.

Now my saved online pages and everything else are gone. So synchronization isn't working.

I have an account recovery key.

Will that work? And how?

Please help me.

Regards, Daniel

How can I restore the FREE ITEM AND GET RID OF SOMETHING I WILL HAVE TO PAY FOR...AND STILL USE ai?

For the last couple of weeks my default search engine keeps changing. Even though I change it in the setting to the one prefer eventually it changes. Why is this issue happening and is there anyway to force my preferred search engine as a constant default?

If a site is designed so that it breaks if trackers are blocked, why would I want to deal with such bad actor? In other words, don't the exceptions to tracker-blocking enable bad website behavior?

Where is the configuration setting that enables javascript. Consumer Reports requires that the application be enabled to participate in a webinar I want to attend

I've used Slack every day for the past decade, and Firefox has been my primary browser for some time now. I've never had an issue with the two, but now, Firefox is reliably crashing every time I attempt to open Slack.

I've tried clearing my cache both broadly and specific to Slack, with neither producing results. Even tried deleting all cookies on Firefox, which was a bit of a pain, and it was no help.

I did read up on some people encountering a similar issue that could be fixed by deleting the Slack entry in "about:serviceworkers," but this did not help here.

The only extension I'm running is uBlock Origin, which I've been running for probably as long as I've been using Firefox, and that has never presented an issue before either.

Would appreciate any help or advice on the matter.

I really enjoy the new sidebar revamp, but I've had an issue with it recently that I haven't been able to find a solution for. Typically, the settings gear is supposed to be situated near the bottom of bar. However, as demonstrated in the attached image, it is at the top near the bookmarks and history buttons. I have tried reinstalling the browser from scratch, turning the sidebar on and off, turning vertical tabs on and off, and even getting rid of my custom CSS theme for a time. None of these have worked. If anyone knows what the root of this issue is, I'd really appreciate the help.
