Firefox 社群討論區

I've tried these extensions:

Don't Accept Image/Webp Image Forcer Webp/Avif converter Save webP as PNG or JPEG (Converter)

They no longer work. Now, Firefox is determined to save images as webp. Researching this problem has turned up a bunch of people saying it's not Firefox doing it, but Opera does not do this. I have always done my work on Firefox and am wondering if there's any way to prevent this or if I just need to transfer all my work over to Opera and be done with Firefox.

So i have trouble with viewing videos directly from google. I often need to go to youtube to view the video. Not a huge problem but still annoying when wanting to just watch some part quick. Here: is a video showing the problem. Do anyone know how i can fix this?

I play a youtube video in firefox browser but it doesn't have any high quality video options. If I copy the link and paste it into the Chrom browser, it immediately has all the options.

Not sure why this https://support.mozilla.org/en-US/questions/1400794 was archived.

Being archived I cannot "check mark" the question to show I too have this problem.

It is a basic problem and a piece of gravel in the shoe of many, I suggest, Firefox users who are developers.

Clearly, there is a need for a UI to navigate inspected content results and the original question author was exactly correct.

This is drip by drip making me want to end my return to Firefox and give up and use Chrome.

Even just an indication such as unarchiving the riginal post and linking to a "Pending to fix" Github issue would be a nice step.

Thank you Mozilla for all you do, and here's hoping this will get looked at.

The time it takes from power ON to loading my homepage (Google News) is now 11 minutes. What can I do to shorten. I've enabled Fox to load homepage on start-up. But it was slow before anyway. My Firefox version is 128.02 My O.P. is Windows 11

If I open multiple Linkedin pages quickly (like when I open a bunch of job postings), most of the time 50-75% of the pages don't load at all or just stuck loading for ever.

I've completely uninstalled Firefox and deleted everything Mozilla related from my Windows 11 PC (including from AppData) but it doesn't help.

The issue persists on all my PC's and doesn't change if I try another DNS provider. I've tried changing a lot of the security settings but none seem to have an effect.

Edge and Brave work completely fine but I'd prefer to keep using Firefox. Any suggestions?

I am traveling in Mexico, connected to a network. I dont speak spanish but my laptop/firefox and at&t mobile phone now do - ONLY Spanish. How do I reset so doesn't automatically pull every website up in spanish?

Hey, so I accidentally deleted a password on my pc in firefox, but on my phone its still "stored" but when I click on the password, it doesnt show it anymore.

is there a way to restore the password? without a backup or anything?

Videos on the NY Times web site never play on my Windows 10 PC, though they do run on my Windows 11 and iPad Firefox. Have disabled all script and ad-blockers without effect. If I click on the Play arrow, I get the circle animation that never ends. Windows FF version 128.0.2 64-bit on both 10 and 11; can't tell what the iPad version is but it works.

Hello support. Since your last update, the "Allow cookie" popup is no longer displayed in the Firefox incognito tab on our site which leads to all functions being blocked. We have tried to identify the problem, but on different computers with the same (current) version of Firefox, we have the result that sometimes the popup is displayed and sometimes not. Why does Firefox block our “Allow cookies” popup in the private window?

I have ordered some goods online and have been offered the option to track the goods. But I can't, because Firefox thinks the tracking page has a fake certificate.

I can go to the website of the delivery company and it has a box where I can enter the order number. This is ambiguous (more than one supplier uses the company) so it lists the two possibilities. I click on the right one and it is at this stage I get the fake certificate warning. I cannot bypass it, because trying to do so simply brings up the same warning.

I've been in touch with the suppliers. Their customer service desk can track the order with no problem. So where is the problem?

They say they can track it using Firefox on Windows, Android and Mac systems but have no Linux available. I only have two Linux systems here (Ubuntu 22.04 and 20.04), running the latest Firefox on offer (128.0.2 64 bit), both of which throw up the fake certificate problem, but with slightly different certificate dates (within the last 5 weeks), older than the genuine cert. I have pdfs of both the genuine one and one of the fake ones as produced by Firefox.

This is not a show-stopper this time as I can track the order by phone and email, but there is clearly a problem somewhere, either with both the Firefox versions I have or with the certification verification process.

If it's a Firefox issue, I don't know how to let them know.

Why is it asking for progress from the script that will apply it works fine on chrome and no progress is visible on firefox
