Diễn đàn hỗ trợ Firefox

I was looking for an item that would be a couple of years back in my history, only to discover that my history now only goes back a year and 3 months… Exactly, as of today, I don't know if that's meaningful. Does anyone have any idea what might've happened, and how I can restore the rest of my history? Thank you!

I'm on a Mac using Mojave, with Firefox version 115.8.

I have to buy a new iMac, which now comes with Sonoma. Is there a version of Firefox that works without major issues on an iMac with Sonoma or is it better to wait? Thanks.

I can't figure out how to delete this extension: Adobe Acrobat. It's disabled, but I want to delete it.

I am trying to print specs for a computer (beck & front) at:

https://www.dell.com/support/manuals/en-us/xps-8960-desktop/xps-8960-setup-and-specifications/back?guid=guid-f2dda353-ba5a-44c0-b85f-6bf1b8c70d15&lang=en-us

The print-out with Firefox captures only half on the picture and relevant info. Luckily, Safari prints correctly. I am wondering why can't Firefox do the job so I do not have to go to Safari for printing? This issue is not specific to this website, it happens often in many other cases. Is this being worked on? Thanks.

For the last several days (as of 12/20/2023) I have had issues with playback on sites including Netflix, Amazon Prime, and Dropout.tv (not YouTube). Error messages indicate that my browser is unsupported and I need the newest version of Firefox, but my browser is completely up-to-date. Pausing my adblocker on these sites does nothing to correct the issue, nor does restarting the browser or my computer.

Comcast (Xfinity) requested that I change my webmail password. I have https://login.xfinity.com on the list of exceptions for cookies and site data to ALLOW. Regardless, Firefox doesn't allow me to do a password reset.

I used Safari to change the password. It worked.

Since I use most of the time Firefox, I wanted to go back and login into Comcast webmail using Firefox with the new password. It doesn't let me and just tells me to reset my password.

This used to work in the past. Something had to be changed since I last changed passwords for webmail in later versions of Firefox.

Please let me know know what to do to enable me to continue to use Firefox for webmail. I have version 115.5. Thanks.

My website (onefishfoundation.org) will not load on Firefox. Instead, I get the "Secure Connection Failed" message with the above statement. This just started happening today. My website loads fine It loads with every other browser.

I've tested my certificates on SSLShopper and WhyNoPadlock and there were no issues on either. I've cleared the cache and history on my browser.

I've closed and re-opened the browser.

How do I fix this?

Thanks,

Colles

I added a screenshot of youtube having flickering while video is being played, it is a bit hard to see but there is a slightly brighter stripe on the grey background and picture cant depict flickering; it starts immediately after video is started and stops after 3-4 sec after video is paused, like there is some background activity behind youtube foreground. I understand my comp is weak (Intel Iris Graphics 550 1536 MB 8 GB, 2133 MHz LPDDR3), but not that much, please help

For the longest time (can't pinpoint when it started) I've been having issues with Firefox on desktop (Macbook) playing videos and occasionally audio. Video playback will be functioning fine, then there seems to be a "trigger"...For ex. I have noticed this is often me trying to play a Twitter video, which won't play normally, and suddenly NO video playback of any kind (and sometimes audio) will work...Youtube, Netflix, you name it.

The only thing that "fixes" the issue (until it pops up again the next time) is quitting Firefox and starting it back up again, usually clearing my cache first for good measure. I have tried disabling all extensions and it has no effect. I have tried playing the video in a private window/incognito—no effect. If I open up Chrome and try to play the same videos I have absolutely no issues.

My Firefox says it is currently up to date, though I am running an older version iOS (Mojave). I have googled and seen many other people having this issue but haven't seen anyone chime in with a fix that actually works. Any ideas?

I am using FF 115.7.0 on a Mac. I normally use tabs but when I need a new window, it opens with every one of my bookmarks in a tab. I can open a subject in a new window from an article in a tab from a different window but I just can't open an empty window without getting all of my bookmarks opened in (many!) separate tabs.

Thanks for any help.

Hi, my shortcuts have all disappeared. I've looked on the browser.newtabpage.pinned and all of my saved websites are listed there. But when I open a new tab they're all blank and I can't seem to add any new shortcuts either. (Also I'm not good with technology so if you do have a suggestion on how I can fix this please tell me exactly where I need to type in a command or whatever because I didn't realise I could do that until just now.) All my bookmarks are still there and obviously it remembers my saved sites so? Thanks :•)

Hi, I just discovered something odd. Trying to troubleshoot something with an android app communicating via web and laptop to free up the phone, and the relevant website has a chat popup and Firefox won't open the popup. I added the website to the whitelist and saved, but still wouldn't. Tried troubleshooting mode, but nothing. Switched to Chrome and it works fine. Cleared cookies and cache and restarted Firefox, but still no luck. The website is ExpressVPN.com. Macbook Pro OS10.14, Firefox up to date, version 115.1.0esr (64-bit).

Is there a way for the new window animation in Firefox for Mac to be disabled?

Safari does not do this, but firefox has a... ~100ms animation for new windows that's extremely frustrating for those of us who do not use tabs (Apple's Exposé/Mission Control obsoletes them).

I haven't found a configuration in about:config, although I've been able to disable a few others.

Animation triggers my migraines.

Man websites use transition and animation timing functions such as "ease in-out" to animate the interface. I try to block this. Among other tools I use userContent,css, including the following:

• {animation-timing-function: step-start !important}
• {transition-timing-function: step-start !important}

This works to de-animate regular css elements, but not ::before and ::after pseudo-elements.

The current css standards do not apply user css to pseudo-elements. I've written to the WCAG about the issue.

https://bugzilla.mozilla.org/show_bug.cgi?id=1865572

https://github.com/w3c/wcag3/issues/40

But I really really need some way to de-animate these, because they trigger my migraines. Aside from css fixes, I often reduce the frame rate in about:config, but can't always do that, disable smooth scrolling, disable animated gifs and animated pngs, disable autoplay, block various non-scrolling elements using either css or uBlock Origin, etc.

about.ef2a7dd5-93bc-417f-a698-142c3116864f.mozilla This ‘cookie’ (no size shown) has been showing up on my Firefox ‘manage website data’ since at least March ’23 and it will NOT delete. It may not be 'a real cookie' but I still can’t get rid of it.

When I searched online for that apparent address I found: https://gitlab.torproject.org/tpo/applications/tor-browser/-/issues/40175 The info near the top of that site’s page: Torbutton INFO: tor SOCKS: http://expyuzz4wqqyqhjn.onion/static/images/home/png/block-trackers@3x.png?h=70991bcb via --unknown--:cc55771ba6d6e8c6542066863a47e223 SOCKS is a username? And the ‘onion/hidden service’ address cannot be accessed unless using the Tor browser? So that seems a dead end for me.

I have seen 3 other people posting here in the past year about this particular cookie. hobro1 did an uninstall & still had to remove directories manually after getting some answers from several others. blazee decided – based on the answer given by jscher 2000 – that it probably wasn’t dangerous. mekishev 1 received an answer from cor-el that is incomprehensible to me, except for saying ‘it isn’t a real cookie’. I understand it may not 'a real cookie' but then why is it showing up in 'manage website data' where everything else is a cookie?

Can anyone help, please? I’m about to migrate over to a new computer and really don’t want to take this with me. I don’t like the fact that it persists, and that the cookies ‘keeper’ – SOCKS maybe? – is completely hidden.

Thanks much in advance for any assistance!

PS The only possible explanation I've come up with for how it got this cookie is when I was checking out some Firefox extensions; I didn’t even know what Tor was till trying to figure this out.

Firefox "Window" drop-down menu is missing open windows. This has happened for a few upgrades. If I add a new blank window, the drop-down menu will fully populate, though if I navigate to any of the other pages, it goes back to being incomplete.

I've had a security breach where a Discord user got access to an email account. I'm going through all computers to make sure there is no malware that might be related to discord. I found one item in my download preferences that says "discord' but everything I've tried won't allow me to erase it. Any information on what this might be? and how/if I should erase it? (In fact, I don't know what any of the items are in my content types)

Is there a way to change the size of the sections in Firefox? For instance, I don't need so much space for the listings of Inbox, Sent etc. or the Tabs but would like to have more space for the web pages themselves. I ask because I've got a sight impediment and have to increase the text size. This means that the web "window" (Sorry, don't know the correct terminology) is so big that I have to scroll down to see it.

Whenever I change my VPN (not Mozilla VPN) status, Firefox will refuse to connect for something like 30 seconds then times out, leaving me with a blank screen. I have wait until that interval has passed before I can retry, otherwise it will repeat the freeze. This happens whenever I turn my VPN on/off or switch to a different VPN server. It happens only with Firefox. Chrome and my email client have no problems whatsoever. I think it's some kind of DNS caching problem within Firefox as the problem doesn't happen if I visit a site that I hadn't visited very recently. There's immediate response if I do that. I have DNS over HTTPS and secure DNS turned off in the settings, so it can't be those.

Anyone else have this problem? I wish there was some way to clear Firefox's DNS cache other than having to go into about:networking
