Diễn đàn hỗ trợ Firefox

I noticed that on Facebook there is not shown data and time on every post. Some posts show this info, the other don't. I cleared cookies, deleted Facebook from history but it didn't help. On Chrome everything is showing normally. I put Firefox in solving problems mode, with add-ons off, it didn't help too. Any solutions?

all of a sudden when I log on to hotmail dot com I get the error message too many requests when I switch browsers to edge I can log on to hotmail as normal

searched the internet but so far have not found a fix

windows 11 and firefox both up to date

I use an addon to mute all tabs by default. The problem is that muted tabs have the MUTED text, which shrinks the size of the tab name/title. My old eyes can't deal with that very well.

Is there any way to prevent this text from showing up globally? Thanks.

When printing double-sided from Firefox 103, the second page comes out upside-down. A previous thread 'Two-sided printing rotating on wrong axis' reported this problem for Firefox 85 / 86, and said that it was fixed by updating to the current version. I have the current version, but am getting the same problem. I have tried manually setting instructions to flip on long side (portrait orientation), but that doesn't work. Help!

Last week I was on a site that I frequently visit. When I tried again today I was denied. I cleared cache and even inserted the site as an exception in the cookies. I tried Edge and was able to log on to the site immediately. Why is FIrefox blocking me all of a sudden?

Just now, I tried to use "Email Link..." under the File Menu and got a pop-up asking me to "Choose an application to open the mailto link." I have seen this before, several times, and usually fix it by going to Tools > Settings, under General > Applications, select "mailto" under Content Type, then select Gmail from the drop-down menu.

This time, however, Gmail is not presented as an option, in this pop-up. Clicking "Choose..." just opens up a Windows Explorer file-picker window.

I tried to fix this in Tools > Settings, under General > Applications. There, "mailto" just shows "Use other..." and if I click that, the "Select Helper Application" pop-up window is basically blank, with a message at the bottom saying "No applications were found for this file type."

I refreshed Firefox but it did not solve the problem.

I have tried to attached images but they will not upload.

I am running v100.0.1 (64-bit) on Windows 11

The hotkey for add-on "600% sound volume" has been broken since the last version of 103. (now 105.0 still not fixed) The hotkey is "Ctrl+Shift+v", which opens the pop-up window of the add-on, and then it allows using arrow key and number to tweak the volume bar. Now all hotkey not working. The arrow keys do not work even if you manually open the pop-up window.

Just installed Firefox my laptop, but when I try to change my search engine to google I only have Bing and DuckDuckGo as my options. No other search engines appear.

I am new to firefox, and not a developer. I have seen articles showing how to install a Language module (done, GB English), but when I right click in a text box all the advice says I should see a "Dictionary" sub menu, but I don't. Spellchecker works in Chrome and Safari, just not firefox. Any ideas...

With certain pdf files, when I go to a page using the outline feature on the pdf viewer or refresh the tab on the same page, the zoom will automatically be set to "page fit". It seems to happen with the title page and table of contents pages. Is there any way to prevent this from happening?

how to remove the annoying thing in top right corner list all tabs make that piece of [removed] go away !!!! now

its the little arrow that points down ! i always show all my tabs so this little piece of [removed] thing needs to go bye bye , why do you always add the dumbiest [removed] nobody needs ! if your going to add something here is a idea also add and [removed] delete button so nobody would have to waste time to remove it !

Hi, I use Firefox, with google.co.uk as my search engine. I have had a problem for several months now, whereby I cannot access images/shopping pages on Google. e.g. I enter a search criteria in Google - say, TOP GUN. I then click on "Images" option, and the "Before you proceed" page opens, ref cookies. I click on "Accept all", but the images page does not open. The same thing happens for "shopping".

I installed Google Chrome, seperately, and it works fine with that, just not with google.co.uk via Firefox. I have uBlockOrigin installed. I disabled it, but still doesnt work (although I just realised I didnt restart pc after disabling it, perhaps I should have?)

Other addons/Extensions are Dark reader, Dark theme for Google, Dark theme for YouTube, and New Tab override (plus uBlockOrigin, as already mentioned). I cleared my cache etc via Security/Privacy on Firefox settings. I used to be able to access these pages, however for past couple of months, no luck.

Any suggestions/assistance would be appreciated.

I've got an old Windows XP computer running version 52.9.0. I'm trying to sign in to Sync (so I can sync with my new Windows 10 computer) but when I try on the old machine I get this error message:

Blocked by Content Security Policy

This page has a content security policy that prevents it from being loaded in this way.

Firefox prevented this page from loading in this way because the page has a content security policy that disallows it.

I've signed in on the new computer, not that it matters.

Is the any way I can connect to Sync?

Hi, Since a few days I have a concern : The Firefox window is surrounded by a thin golden yellow line. In full screen mode or not, that's always visible. I searched the web but couldn't find any conclusive solution. If you know please tell me :) It really annoys me :) Thank you.

I need to change my E-mail adress but cannot get into my Firefox account because they keep sending unlocking codes to my old adres that is no longer active. Please advise.
