Diễn đàn hỗ trợ Firefox

I was using Lightspeed today, and the website pops up a confirmation dialog box (probably through JavaScript) so that you can confirm that you want to do a specific action. I got annoyed with the dialog and clicked the included "Don't allow this website to show prompts anymore" box when I hit OK. But now it won't perform any action that requires you to hit the OK in the prompt, so I need to make the dialogs come back so I can do my job. I can't find any setting anywhere in the browser that I have actually disabled or changed by hitting the box in that prompt.

In the Microsoft Store there are all these updates for video extensions like "AV1 Video Extension". Should I be doing these updates? Do they make any difference to streaming video on the Firefox Browser?

For whatever reason the Picture-in-Picture button keeps not showing up in normal places like Prime, Netflix, Hulu, etc. I can make it come back by going to the Settings turning off the Picture-in-Picture option (Which is always still active) refreshing the settings then going back to Picture-in-Picture and turning it back on and then finally refreshing the video I was trying to use, but this is kind of a lot to have to do every time it happens and it seems to be happening more and more, so I'd like to fix the root cause instead if possible. Any ideas?

Using text boxes such as comment sections in certain sites will "duplicate" the boxes directly over it Scrolling up and down will lock the boxes on screen and leave multiple traces of the text boxes Refreshing the page will remove the boxes temporarily but will happen again Happens inconsistently on multiple websites Site shown under is dcinside.com

Using Nord Pass extension on Mozilla fine until today, when clicking on the green icon for stored username and password, this appears - "sudden error message : can't handle ITEM/URL_SEARCH type message"

YouTube won't start playing in Firefox. No add-ons enabled. The page is fully loaded, but clicking on Play makes nothing.

The fix is to disable "User recommended performance settings" and then disable "User hardware acceleration when available".

The problem is that hardware acceleration is enabled by default. In Edge or Chrome hardware acceleration is also enabled but it won't break YouTube.

Apprantly Firefox updated last night. I still show all the names of my bookmarks but NONE of them have any information in them. Probably lost my passwords too.

Tried all the fixes shown in prior posts. This is unacceptable !

I made a mistake and installed Firefox in the wrong location. I uninstalled and attempted to reinstall where I wanted the software to be.

The installer now tells me that I had Firefox before and will only reinstall it in the previous directory. No other option is offered.

I am LONG used to being deprived of user choice by the likes of Microsoft or Apple, but Mozilla SHOULD KNOW BETTER.

Can you help?

Thank you.

For the past few days, when I try to log on to PlayStation on Firefox, the sign-in page sits on a loading swirl after inputting email. There's a clear memory leak shown on Task Manager. The menu bar's right-click doesn't draw properly. FF can't be closed and needs to be terminated. The only extension I have is uBlock Origin disabled for this site.

This website works on Edge.

Attached is the broken menu from right-clicking the menu bar.

In the past when I reinstalled Windows and then Firefox, I would sign into my account and all my bookmarks/addons etc. would automatically get reinstalled. Today I had to reinstall Windows and when I logged into my firefox account, nothing happened. Does Mozilla no longer keep these settings for us? I don't have any other devices to sync off of and never have, so where did all those settings come from when I did previous reinstalls?

everytime you update firefox, i loose my personal toolbar that took me a long time to set up. how do i get it back without all the work? also, what happened to the printer icon in the main toolbar?

The website https://my.strathspey.org/dd/dance/12838/#cribs displays an image, which had a typo [Triangles used to be Traingles]

I am using Firefox 119.0.1 under Windows 10 Home Version 22H2 OS build 19045.3693

I had the page open in Firefox before the owner corrected the typo.

Immediately after the correction was online, all other browsers displayed the corrected version. But even now, hours later, after many resets by "Reload Tab", the Firefox tab still displays the typo-version.

I consider this to be a malfunction. "Reload tab" should bypass all caches, and reload the whole page directly from its server. - Is this a known bug? - If "Reload Tab" does not go to the source bypassing all caches, what doe it do? - Is there a workaround?

its the browser, the opperative said when I phoned in about no access. try chrome, they said and true enough it worked. Just shy of 15 years with firefox and now nothing but problems, the cut and paste does not work and now this! pointless staying with them

I want extensions to have white/black-lists, so they're only allowed or blocked on certain pages e.g facebook container ruins instagram experience... and I can't block it on *instagram.com* Such feature would significantly enhance UX on firefox

Thanks, Rob.

I have a personal ' writing email' template in Yahoo mail which I use for a specific community. It contains relevant information which saves me from having to type it in everytime I email the community. However, of late when using 'Compose' the template appears but when I try typing below the salutation I cannot use the 'Enter' button to move the cursor down the page to create the body text. Consequently my emails are just one line of type with no paragraphing.

Why is this?

Is there a way I can disable the "Pop out this video" button on the video player itself but keep the toggle present in the url bar? I have attached the pictures of what I am talking about I don't like the pop out button appearing on the video everytime I try to use my mouse around the video player but like the option of picture in picture seems like a good option for me.

Currently if I try to disable the button from the menu after right-clicking, it also disable the button present in the url bar.

My Windows Task Scheduler contains an entry called "Firefox Default Browser Agent". If I delete it, it returns. If I disable it, it re-enables itself. Can't be modified either. How do I turn it off permanently?

I already have telemetry and automatic updates both turned off.

In about:config default-browser-agent.enabled is set to false
