i'm on windows. Suddenly, PDF files that I open have black pages. I checked that the default setting is to open pdf files in Firefox, as always. refreshing doesnt work. Any ideas what is wrong?

I cannot see any of the content or text on PDFs when I open them with firefox. The content and text is still there and I can copy and paste it onto anther document, how can I fix the viewer to be able to see the PDF content on Firefox?

Yesterday I was on the Newsmax website. Today Firefox says its not a secure connection and it won't let me go to Newmax.com. I then tried to use the google browser and it went right to Newmax.com no problem. I am using Windows 7 like I have been for years. Please help. Thanks, Al

The camera won't turn on in the Firefox browser for Google Meet or Zoom. It says it can't find the camera or that it's turned off. I have checked my Windows 11 settings and desktop apps have access to the camera. I have also checked the settings for each of the sites and use of the camera and microphone are allowed. Autoplay is enabled too. The camera works fine in other apps and in other browsers.

Team, I am a longtime user and supporter of FF. I can't tell you how much I love the the layout of Firefox on Windows in v. 133 with the vertical tabs. Just as important is the fantastic, new font rendering. Thank you so much. I used to make multiple adjustments to the font in about:config when I installed FF on Windows. Now, the fonts look fantastic out of the box. Great job, team!

Lately, my Firefox browser does not play videos from Dailymail.co.uk. What seems to be the problem? It had been working so well before this until the last few months. I also have an ad block plus extension which I disabled for this site but nothing seems to work so far. I do not have a problem with Microsoft Edge playing videos from the dailymail. Any help?

I am encountering an issue with the Ultimate Addon Image Gallery when viewed in the Mozilla browser. On the user's first visit to the page, the image gallery fails to load promptly, often taking a long time to display. During this delay, a black screen appears instead of the intended images, and the images do not retain their original sizes.

This issue is specific to the Mozilla browser and impacts the user experience. I would greatly appreciate any guidance or troubleshootinghttps://globalstep.com/art-page-revised-v6-33/

When is Firefox (across devices) going to bring "Tab Groups" in-built in 2025 as it is difficult to ditch Chrome esp., if it is related to work or research and similar tabs are opened up?

I have to rely on chrome and edge for same and both have not only brought it but improved it considerably. Also, chrome has not brought for mobile devices so grouping of tabs is more easy and simple but when I look at Firefox and Firefox based browsers, I see nothing of that thing present. The addon esp., Simple Tab Groups (https://addons.mozilla.org/en-CA/firefox/addon/simple-tab-groups/) is unreliable (see reviews).

If Firefox want us to use their browser and as default, they should see why we are using Chrome and Edge (latter, having vertical tabs in-built, also).

I hope 2025 is a year Firefox learns of how to retain users across devices. Currently Firefox is more from 2005.

Browser Choice Alliance wont be helpful if browsers like Firefox dont see users and their reviews and posts and issues reported. "https://browserchoicealliance.org/"

3 years post and still no work, and Firefox wants us to use their browser over Chrome and Edge. Why? And how?

On the newest firefox update on Windows PC My PDF reading has been not displaying PDFs correctly on Firefox I tested on other PDF views and they work as normal (All images are normally white with black text PDFs) Sometimes it displays nothing at all (as seen in Image 1) Some pages will display correctly but the rest won't (as seen in Image 2) Some pages will display text but strangely (as seen in Image 3) It does flash white sometimes while scrolling but it still doesn't show text

When on a web page or e-mail I regularly get a spinning multi colored ball which stops/interrupts the loading of the page. It will last for 3/4/5 seconds and then stop. What's up ??

I want to delete all my bookmarks at once -- I have nearly 1,500. I already asked this question and the response I got showed me how to do this by selecting each one at a time. I want to delete them all, AT ONCE!

Not selecting each one and holding down the CTRL key.

Btw, I already explained this ... so, is there a way. I've tried uninstalling and reinstalling and not keeping the former settings. But the stupid bookmarks keep coming back!

My hotmail Email page stopped opening yesterday morning. I can open the Live.com page on my Android phone and Safari. I Don't like Safari, and I want to be on Firefox on my desktop.
