Diễn đàn hỗ trợ Firefox

I always use the current Firefox on two Macintosh browsers running OS 10.14.6.

Recently (in only one of the computers), if I download a file, a pane containing recent downloads opens in the upper left-hand quadrant. This is distinct from the downloads portion of the "Library" area, and gets in the way of my ability to use Firefox efficiently.

I can't seem to find a way to keep this pane from repeatedly opening up as I download things. Can anyone help?

Suddenly, when I search the web with a topic search term, e.g. "thrombin", I get the error message: 'The page you are looking for cannot be displayed because an invalid method (HTTP verb) is being used.' Can you help me resolve this problem?

Having any google related webpage open for more than a couple of minutes causes it to disconnect (gmail, calendar). This results in no connectivity to any Google services. Opening new tabs will refuse to load even Google.com. The only fix is to completely close out of Firefox and relaunch. But having gmail open for a few minutes will result in it disconnecting again.

The issue persists in 'troubleshooting mode' as well as after doing a refresh. I have experienced this now for the past couple of weeks on my Windows 10 work laptop. I have also seen this on 2 different Linux machines in the past few days. I had attempted to disable http3 and telemetry settings from an older post I had found, but no luck. Not sure what else to try at this point.

When I modify my website, the updated version shows fine in CHROME and EDGE but shows my old version in Firefox. I cleared browser cache, hit reload numerous times, relogged, all the usual things I could think of.

Have any helpful info?

I got mad at a website that wouldn't let me right click menu to save pictures, so I stubbornly saved them via less efficient means, in the process I picked up the Long Screenshot extension and this had an error shortly before or after I had an issue with Lightshot not appearing, other extensions did not appear either when I added them during this time period, but now these all appear with the exception of Lightshot, which gets deleted and reinstalled only to not appear, that of course being the problem, though I will also say that a right click menu not being there is like reaching onto my computer and pulling my finger away, sites that do that should be given the cold shoulder somehow, at least.

The Firefox desktop browser default font is replacing all fonts on some websites, only title fonts on some others, and then leaving others unchanged. It seems random, and I can't stop the default font from taking over randomly on most websites no matter what I do. This was not happening until today, and no browsers or general MacBook Air preferences were changed between today and yesterday when I last used the browser on desktop.

Under Firefox Preferences » Fonts » Advanced, I've made sure to check the box to "Allow pages to choose their own fonts instead of your selections above", and I've unchecked it, and I've re-checked it, and the default is still overriding fonts on most websites.

I've quit and restarted Firefox 3 times.

Help!

I need to turn off my Delete cookies and site data when Firefox is closed setting.I have wrongly turn on this setting i need to turn off this setting.please help me to change it.

I was using Ctrl+K on some websites to do things like site-specific search, task bars, and so forth, but recently Firefox started capturing it for focusing on the search/address bar (https://support.mozilla.org/en-US/kb/keyboard-shortcuts-perform-firefox-tasks-quickly#w_search).

Is there a way to unbind `Ctrl+K` in Firefox?

This problem just started today. I am very angry. what is going on with Firefox? Websites are filled to the brim with annoying ad's. and you tube videos are constantly interrupted with ad's!!!!! What is with all the ad's? This problem has not existed until today. Please STOP this! And, No, I can not just wait a few seconds then click on "skip ads" because I am looking at videos on a computer screen while sitting away from the computer in a chair so constantly having to get up, walk to the computer, click on "skip ads", walk back to my chair is an annoyance! Just stop with all the ads!

When playing videos on youtube or any other platform the volume is very low to non-existent. When a new video starts there is a sudden surge, whereafter it rapidly returns to a non-audible level. I have tried checking the volume settings in Windows and Firefox but nothing has helped thusfar. Please help me resolve this issue so I can go back to using my favourite browser again.

Thank you in advance!

I have seen this in some past versions of FF It usually goes away after a few upgrades

Instead of whatever it's supposed to display, you can see that it shows some random characters.

Annoying. I dont even remember what it's actually supposed to show

The background on the homepage link shortcut boxes keeps reverting to black and text underneath to white on my off-white background when a new version loads. I've used Colors to customize the look of my firefox but can't find any control for that. Once a new version kept the boxes white and the text black but now it's back to black again. Where is the control to fix this?

I can only save (not open) Gmail attachments after the latest update and JPG is not showing up in my the Applications section of Settings/General so I cannot fix it.

This has happened one time too many guys, every update but this time half the items I would normally get as an attachment are no longer listed in the applications menu.

If I cannot get a fix quickly I will be forced to move to Chrome (which I REALLY hate the idea of). I see 25 - 80 emails a day and it is mission critical that I can open and view email attachments without having to save them.

A little help??

Normally there is no difficulty searching a pdf with a pdf reader. How does one do it in Firefox?

Note that ctrl+shift+f and ctrl+f do not work.

I have set the Noto family of fonts to be the default font family but websites that don't specify a font or specify sans-serif or monospace get Liberation Mono. When I changed any option in the fonts settings, the entire browser becomes Liberation Mono. I want Noto Sans be the default font for websites and for the Firefox UI. I tried to fix it by preforming a Firefox Refresh, but it didn't work. I think the problem began after upgrading to Firefox 100 but I'm no 100% sure.

I use firefox since I go to college. When I got some problems, I try to check firefox use what to pick folder? I use Manjaro Plasma. I find chrominum use kdialog. But firefox looks not though both use gtk3 as UI

Firefox choose folder got wrong when use a USB HDD

Is it possible to move the address bar above or below the Bookmarks Toolbar in Firefox 100.0 (64 bit). If not, can you provide a link to the latest version of Firefox for Mac OS X Catalina (10.15.7) that does not have the address bar on the same level as the Bookmarks Toolbar.

Many thanks.
