Hi I am losing all my windows and tabs within these windows when Firefox does updates.

I lost 3 lots of windows with tabs just before Christmas 2022 and about two months ago they all appeared again after an update, I was so happy, then about 1 hour ago I found another update was done today 28-5-2023 and now I have lost them all again. But another group of 2 windows including tabs that I lost about two & a half month ago turned up instead.

Are you able to help me find the disappeared windows/tabs and be able to keep these windows & tabs until I am finished with them, it is very annoying

Thank you Regards, Doug

Everything is wrong as below. -

Just downloaded 113.02 Firefox. Frame around firefox windows and tabs loses Min/Max, "X" exit button and full screen buttons. Coloration of the frame also changes from solid to opaque and back without any input from me. Does seem to vary based on memory usage. High usage appears to cause these symptoms but can't be sure. Controls do not reappear. Double-clicking the frame makes them reappear only momentarily. Uses Windows 7 Pro OS.

Is there any way to turn off the button "Open video in a new tab" that appears when you hover on an Instagram video? This button is blocking a button from an extension that I want to use.

I'm trying to use multi-account containers to use twitter and other sites from accounts unique to the container.

For twitter, if I select a container, a new tab opens with the twitter login page in that container. If I try to login, another tab opens in that container, with the login page. So, I can never log in.

Is there a solution?

In our site we trigger popup window with form being submitted with POST method and target="_blank". This is done so it opens 3rd party web app in new window. However, when popup windows are blocked for our page it (correctly) blocks popup, asking user if it should allow popup window. No complaints here. However, when user allows page to show popups, or allows for a single popup, while it opens in new page - it tries to open the URL with GET method, and not with POST, as originally intended, breaking our app. Now of course user can just re-trigger the form and now with allowed popups it will work. But should user not want to allow all future popups to be shown, there's no way for them to open a single popup with firefox switching method (and possibly losing form data?)

I have an intermittent problem with the back and forward buttons skipping pages. My home page is a blank page. From the home page I select the YouTube bookmark. I intend to right click on a video and select Open Link in New Window, but sometimes my touchpad doesn't see it as a right click and opens the video. When the video is done if I click on the back button, the browser takes me to the home page (blank) instead of the first YouTube page. If I then click on the forward button, YouTube loads a new page of videos to watch. There is no way to get back to the original first YouTube page which is annoying if there was something else I wanted to watch. I've had this happen with other sites as well. I originally thought this was a Firefox issue but now am wondering if my touchpad is interpreting the click on the back button as two clicks and causing it to go back two pages. Is this possible?

Is it possible for Mozilla to add a setting to Firefox that blocks .zip and .mov links from ever opening even if clicked on since a big part of the .zip links are being used to infect computers with malware

In windows 10 I have disabled ClearType antialiasing. Because of this, Firefox does not make antialiasing of some fonts: Firefox-Google Firefox-Wiki

On the same system, Chrome browser does antialiasing (grayscale): Chrome-google Chrome-wiki

How to force the Firefox to use antialiasing the same way as Chrome?

Firefox is 113.0.2

Hi there I love FireFox, after years of others recommending, I finally switched and really appreciate so many great features (automatic downloads not at all though). Anyways, I have a Tivo with in house and out of house streaming to Watch Tivo web app and Tivo android app. Until recently, was able to stream anything from Tivo Box throughout house. Android app works awesome, but no longer working on FireFox (or Edge & Chrome) Research shows this is due to a change in website security which is maybe similar to FF issue?

Chrome offered advance warning/remedy..as detailed below....

I am hoping FF team can rise to the challenge and get tivo online working again for the millions of us who still use and love our Tivos.  Or maybe another Tivo fan has a workaround they can share? I sure hope so, I have wasted hours already troubleshooting and hair pulling :(     Any and all assistance appreciated

Access to XMLHttpRequest at 'http://(MYIP):49152/sysinfo/json/svcinfo' from origin 'http://online.tivo.com' has been blocked by CORS policy: The request client is not a secure context and the resource is in more-private address space `private`.

After researching that i found this link Chrome CORS error on request to localhost dev server from remote site

it went into a bit about how "Chrome has implemented CORS-RFC1918, which prevents public network resources from requesting private-network resources - unless the public-network resource is secure (HTTPS) and the private-network resource provides appropriate (yet-undefined) CORS headers."

So basically a public network "online.tivo.com" cannot access my local network (where my tivo is) due to this new CORS-RFC1918 standard.

The is a fix to disable this behavior for now chrome://flags/#block-insecure-private-network-requests

Last week, mid-day one day, videos on YouTube suddenly all had a warm cast --yellowish for color, cream/beige for B&W. I have researched the issue as I can. It is not my Windows night light; my drivers and PC are apparently all updated; everything is working fine. I checked to see if the same happened with Vimeo videos and it did. I'm running W10.

   Interestingly, the pop-up thumbnails one gets when hovering over the timeline as not affected; they look fine.
   One post by someone else was answered that it was a GPU driver issue; another said it's only with HD videos.
   I'm a B&W photographer and would really like to get back to normal again. 
   Any ideas?

Not secure website home accessible, but none of the pages under it. Unable to mark pages for not secure browsing. I marked the home site for not secure browsing OK. But no pages under it will open. There does not seem to be a way to tell the browser to ignore the security requirement for all pages in this website.

I just got an add-on called LMMS Music Studio. But every time I click on their icon I am taken to something else called "https://www.offidocs.com/edit-lmms.php?username=810908&fileurl=newfileoriginal" Any ideas?

Hello dear Firefox Community,

I have been trying for a while now to set up a proxy on my own and have Firefox connect to it. Since there are a few options on how this can be accomplished in theory, the only way I way able to get it working was by using an Http Proxy. I looked at the connections Firefox is initiating towards the proxy using Wireshark. I was shocked to say the least. When trying to use an HTTPS Proxy, Firefox doesn't encrypt the connection to the proxy at all. So the domain I'm trying to connect to and the Credentials I use to log into the proxy are visible in cleartext. That is an absolute No-Go! Is there a way I can configure Firefox to encrypt the connection between itself and the proxy? If not, are there any plans on implementing this kind of functionality?

Hi, By accident I changed a setting somewhare and now I can't share screen when using Google meets. I use a MacBook Air M2 2022 and run version Ventura 13.4 and Firefox version 113.0.2. I have googled the problem and had help from Apple support so I have already; - checked settings in my Mac - checked settings in Google Meet - deleted cash memory in Firefox - rebooting my computor - run Google Meet in Safari and screen sharing works

I don't dare to reinstall Firefox because then I will lose lots of data. What have I not done that this community could help me understand.

Thanks in advance.

Best, Fredrik
