Firefox 技術支援討論區

Some websites like youtube, twitter, reddit and maybe many more don't properly load. On youtube videos freeze after a couple of minutes, I don't have any of these other issues on other browsers like Chrome

Hello, FireFox Updated my 17" MacBook Pro- High Sierra on July 30, 2023 successfully to 115.03. There was another update today Aug 1st 115.1esr, which said it Failed for an unknown reason. Can anyone tell me how I can find out what happened? See attached update message.

Thanks in advance for your help.

My previous version of Firefox was on the fritz and I was afraid there was malware in it so I uninstalled it. When I reinstalled it I realized all my bookmarks were missing and I can't figure out how to restore them from my profile or a previous backup. Please help! Thank you.

I have a question about the same topic of this older thread here -

https://support.mozilla.org/en-US/questions/1257189

...when you do some of the solutions to this problem the copy-and-paste from either the vertical column or in Bookmarks manager it will copy the whole URL code as the title of the link and not what you renamed that link or its default name from its creator.

Is there a way to copy-and-paste the bookmarks WITH the already-created link names attached from the previous Firefox / Waterfox browser?

After removing other elements, I'm left with a map, which I was able to expand to the top and sides, but not the bottom area.

The site is https://earthexplorer.usgs.gov/.

Just to preface I have already tried looking for a similar issue in support and most of the answers are like "just make sure to not be in private browsing" but I am sure that I am not and my extensions are all allowed in private browsing anyways. I also know this is not a theme issue as after I removed ublock origin and re-added it to firefox the extension icon showed up in the menu just like usual, but I do not want to do this for every single extension as I have a large amount and I am worried about personal settings that I have saved being undone. In the past I have used this same firefox setup without any of these issues whatsoever and without changing any settings since then.

The main issue is that when I click the extensions menu toolbar icon (the puzzle piece) it only takes me to about:addons. On this page I can confirm all my extensions are there, and I know that they are working, due to things like ads still being blocked from ublock origin or tracking links being blocked from clearURLs. However there is no icon for them after clicking/right clicking the the extensions puzzle piece, or when using the "customize toolbar" feature, or in the overflow menu, or in any other possible place. I have also tried telling the toolbar to reset to default and this does not help. Since the puzzle piece icon never shows me a menu, there is no way to right-click an extension and get the menu option to "pin to toolbar" as this option can't be found in the about:addons page as far as I have found.

Is there any way to fix this beyond just re-adding every single one of my extensions?

Hello there, I'm getting following warnings when I set report-to directive.

Content-Security-Policy: Couldn’t process unknown directive ‘report-to’ Content-Security-Policy: This site (http://puvipavan.local) has a Report-Only policy without a report URI. CSP will not block and cannot report violations of this policy.

These are the passed headers:

Am I missing something? I'm using the latest version of Firefox as of July-31-2023(115.0.3 (64-bit))

I want to disable overscroll. For those who don't know: it's the bouncy animation when you use scroll using a two-finger gesture past the beginning or end of a scrollable region.

The bouncing is an animation, and with animations disabled on my system, having this animation is an accessibility issue.

I guess I could split this question in two:

1. Can Mozilla please change Firefox so that it doesn't do this animation when animations are supposed to be disabled? 2. How can I disable this overscroll behaviour manually, separately from other animations?

After updating a W10 laptop from 115 to 116 of FF the user started having problems with getting to different websites (sites they worked on/with regularly). The problem is the cert DB. The doc I found says that it is cert8.db. Actually it is now cert9.DB.

What I had to do was go to task manager and kill a task that was holding the cert9.db file. Then I could rename it (cert9.old.db). Then restarted their laptop and FF came up and started fixing the cert file (as expected). This seems to have fixed their problem.

My windows install in my dualboot pc is unable to open at the moment, I can access the windows files from my linux. But i need the firefox data on that pc that I kept. I don't remember which email I used on that account so I'm kind of stuck on getting my data from online. Is there a way to recieve all the data from another drive without opening firefox?

I have four active Firefox windows, each with quite a few tabs. I have been closing and re-opening Firefox with no issue until today. Earlier this week I updated my Mac OS to Ventura 13.5, and Firefox was still operating normally after the installation (closing and re-opening with all windows and tabs intact).

Today however, when I restarted Firefox, no windows opened automatically. I closed and restarted a few times, and finally one window opened intact; however the other three windows (still dispalyed on the "Windows" menu) refuse to open. When I look at my Firefox app on my iPhone, it also shows all the tabs intact.

What can I do to get these to open? I am running Firefox version 115.0.3.

I am a backend developer (API maintainer) and I use firefox as my primarily browser at work. A feature that I would find very useful would be that firefox prettifies the "Form Data" under the "Request" tab when a request is selected under the "Network" tab in the developer tools, and with prettify I mean to display in multiple lines and highlighted properly (for a comparison example you can take the "Postman" application feature under the "raw" tab).

As of now it only displays the form data in a single horizontally scrollable line and it also has a "Raw" toggle.

Thank you and keep up the good work.

so i have sync enabled on both devices and evrything sync perfectly except the tabs opened on my iphone are not showing on synced tabs section on my desktop firefox but the open tabs on my desktop frirefox are showing on my iphone synced tabs section btw i reset sync and signed out and signed back in and everything synced but my iphone open tabs still not showing on my desktop client

The spell checker isn't working for me. I've found old answers to this:

"You can see which dictionary is selected if you right-click in a text area and open the Languages sub menu. At least one dictionary should be installed and have a check mark to indicate that it is selected.

   open the "Add Dictionaries" link to install a dictionary if you do not have one. 

The spelling checker is enabled if [X] "Check Spelling" in the right-click context menu has a checkmark.

You can enable or disable spell checking globally:

   Options/Preferences -> General: Language and Appearance: "Check your spelling as you type" 

You can look here for dictionaries:

   https://addons.mozilla.org/firefox/language-tools/ 

Note that for spell check you need a dictionary. A language pack provides string translations for the user interface.

   https://support.mozilla.org/en-US/kb/use-firefox-interface-other-languages-language-pack 

You can check the layout.spellcheckDefault pref on the about:config page.

   http://kb.mozillazine.org/layout.spellcheckDefault "'

But I don't understand what most of this means!

I don't find 'language' because I don't know where to find a "text box containing more than one line" I'd have thought this was one, but the option does not come up here when I right click.

I realise this is probably me being dense, but can someone help in simple terms, please? Thanks.

Websites displayed in Firefox use ridiculously low contrast for their text. This composition box is a prime example. 30 years ago when my eyes were 30 years younger web sites tended to use BLACK TEXT on WHITE BACKGROUNDS, with fairly THICK FONTS.

Over the last 5 to 10 years websites and/or browsers have adopted much the terrible Apple Style used in its packaging: Light Gray Text on Lighter Gray Backgrounds *and* very Thin Fonts. Fortunately websites/browsers have not yet generally followed Apple's lead to the use of about 4 point fonts.

    I'm using:
         * Firefox Browser 115.0.3
         * MacBook Pro 15"
         * macOS Monterey  ver. 12.6.7

How can I greatly increase the contrast and the density of text displayed by the Firefox Browser?

the download complete sound is too damn loud, is there a way to disable the alert? i use my computer connected to my tv and so far the only way i have found is to mute the system volume. i am looking for a setting in firefox to change.

I've tried all the ways mentioned to delete my search history, other than deleting each entry individually. Three particular websites just won't go. Is there some umbrella action that will delete all these references?

Firefox .pdf viewer has documents shifted too far to the left. there is no way to center them with the tool even reducing the doc. from 100% to say 80%, they remain too far to the left. without any left side margin, any printed doc. that must be 3 hole punched for a LL binder, has data punch through it. this doesn't happen with any docs. printed directly through hotmail. they are centered correctly but any .pdf, even downloaded say through Adobe Reader but opened with Firefox will have the same problem Why? thank you, Michael

Every time I log on a site where I have previously searched something in their search bar, whatever I searched either gets auto-filled (even if I want to search something else) or appears in the bottom of the search bar. They disappear if I clear all my search history but then I have to re-log into every site on my browser.

How can I delete those suggestions/make them not appear anymore without loging out? I have tried checking the autofill settings but everything is password related.
