Diễn đàn hỗ trợ Firefox

Hi, Windows 11, 32GB memory. Firefox crashes regularly when between 1.6 and 1.9 GB is consumed It happens when watching YouTube. What is the solution, please? Thank you.

A website that I have used for years to track my wine cellar invenory has ceased functioning for me. The Web Designer tells me that the problem is a network issue and not his problem. I get no solutions from my ISP.

When I attempt to load the page and look at the Console I get the following error message in response to several GET requests:

Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at https://cdn.ct-static.com/dist/js/ct.min.1530c2da96.js.

A web search tells me that this policy is a browser safety net. Any suggestions for troubleshooting?

I have a drop-down list on a website of things I regularly search for, but alas, some of them contain typos and I'd like to be able to re-order them. How can I do this on Firefox 146.0 (64 bit) under Linux?

I started using the new "Profiles" feature in firefox, and I created profiles one one device. However I am finding that the profiles are not syncing across my devices. Both are Windows 11 VMs, I tried doing manual syncs, singed out and back in to both devices. But the Profiles I create on each just do not seem to sync, is this the expected behavior ?

Accessing Planefinder.com. Have done so many times. After checking on a flight multiple times today, I acquired a notice that said I was blocked from accessing. Is this a scam? It says I entered a word or phrase that was unacceptable and thus am blocked. I can still use Planefinder on my cell phone. I only enter the plane information that is called for. What is going on?

Hi. I have all the automatic opening of the last session turned on. So for the last two months, when I fired up my PC, all the tabs came back on. That is, until today!

Because I mistakenly clicked "X" when I had private browsing on in other window.

This created error that resulted in blank screen coming in... All my tabs are gone, and they are not in the recent history. How can I bring them back on"? they were just there not 10 minutes ago.

I am just burned out with Firefox and not sure why I should continue to use it instead of some fork or Chromium-based browser.

It seems like every update brings some new GenAI/LLM component that is auto-enabled and difficult to disable. I do not want GenAI/LLMs in my web browser. I have dropped nearly every other application or software that has forced it on me and included it in their product. I feel like I'm trying manage a Windows system having to follow blogs to debloat, restore privacy, and restore security. GenAI/LLMs shouldn't be in my web browser. And, they should be opt-in, not opt-out in some confusing mix of GUI and about:config madness. If GenAI/LLM is so great, then make it an extension or a fork then let those folks use it from there. Don't bake it into the web browser.

I continue to use Firefox for uBlock Origin but I guess that would be possible with a Firefox-fork. However, I am just tired of having to continuously manage my Firefox browser and battle websites that only support Chromium-based browsers. If Firefox actually seemed intent on improving security and privacy then I could find the motivation but this GenAI/LLM nonsense seems the point of no return.

On my Android phone, I've switched to a Chromium-based browser given the poor state of security and hardening for the vanilla Firefox. I keep IronFox on hand but it is just easier to surf the web with a Chromium-based browser due to many websites just working better. Why should I deal with the pain and frustration of limited Firefox support when Firefox isn't even keeping up with security hardening?

As for desktop, the Firefox browser just doesn't seem as snappy or stable as I would expect. Firefox for Linux is still not supported for Slack Huddles. How is it 2026 and Mozilla/Firefox are still not fully functional with one of the major business chat platforms? Yes, I know this primarily a Slack and AWS-Chime-SDK problem but it is also a Firefox problem because there isn't much that a user can do. I've tried to prod Slack and the AWS teams numerous times to support Firefox but they've just done nothing. I also see nothing being done by the Firefox team, too.

Another example is the EdgeSuite CDN. Nearly always they block my traffic when I use Firefox. Switch to a Chromium-based browser and EdgeSuite is much less likely to block me. This is fairly consistent for the retail and financial institutions I use.

As far as I am aware, many of the security concerns brought up by Madaidan in 2022 still hold true for Firefox today, especially for Android and Linux. If this is no longer true, then it might be good for the Firefox team to post a rebuttal or update clarifying the current state of Firefox. The average users such as myself only see the Madaidan blog post and have to take it at face value. https://madaidans-insecurities.github.io/firefox-chromium.html

Anyway, I don't see a way ahead for me and Firefox but maybe you can convince me. It just seems like Firefox and Mozilla have lost their way. They no longer seem focused on security and privacy. Instead they're forcing privacy, security, and system resource disasters onto their userbases, just like Microsoft, Google, and every one of the major tech firms. I just don't see why I should use, promote, and even support Firefox going into 2026.

Trying to log in to citizensbank.com. After I enter username and password, logs me in and immediately logs me out. Suspect the bank is doing something tricky, but an hour with their tech support didn't get me anywhere. As usual, they blame Firefox. Anything tricky I have to do I Firefox to counteract their trickiness?

For some reason after I restarted my laptop (firefox was opened) Mozilla was reset. I was logout from my acc and also firefox isn't my default browser (I didnt anything with it). Btw if I tried to open any link system will open it via firefox. But firefox still said that its not default browser in system. And if I open default apps in Windows I have 2 firefox there (and both recommend me to set is as default). Except FF I have only edge that also said that I can set is as default. After I login in my acc in firefox I haven't anything. No history, no passwords, extensions etc. What I can do here? I tried to use sync but as result I still have nothing.

Never cough smth like this before in same cases.
