Firefox 技術支援討論區

Hi, I really love everything about Firefox Developer Edition, except the JSON viewer. I'm used to looking at plain formatted JSON like the JSON Formatter plugin provide. But, even thought I have installed JSON Formatter (https://addons.mozilla.org/en-US/firefox/addon/json-formatter/?src=recommended), it only shows this tree/table-ish viewer that comes with Firefox Developer Edition. Is there any way to disable this feature and use a plugin for this, just as in Firefox ?

I just signed up for Firefox Monitor. Most of the accounts it says were breached are ones I recognize, and I have changed my passwords. However, it also says there were data breaches affecting two sites I do not have an account with at all (Whitepages and Verifications.io). What do I do about those, since I haven't got an account (I don't even know what Verifications.io is), so I don't have a password to change.

I am comparing different browser-based password manager implementations.

I noticed that Firefox prompts to remember credentials when a form is submitted, but some other browsers, e.g., Google Chrome, wait until the server responds with a success status before prompting (and, if the server responds with an error status, then the browser does not prompt to remember the credentials).

I assume there are pros/cons to these different approaches, and I would like to better understand the trade-offs.

Right now, all I see is that it is possible—even likely—for a user to tell Firefox to remember an incorrect/invalid password—which seems like a downside to Firefox's approach.

Hi all, I am experiencing an issue where some site (such as google and asana) think I am on my phone. Other sites do not do this, but several that i use regularly do. I tried troubleshooting, and i noticed that when i use a private browser, google and asana look good on desktop, so that is why i think this is a firefox issue. Ive tried searching google and the knowledge base but all the searches think I WANT to view the mobile view on desktop (to check responsive design most likely), but I actually want to STOP seeing the mobile view on desktop.

NOTE - this seemed to happen right after I selected an ad to be hidden using the AdBlock extension on an article i was reading. i dont know if this is relevant or not, but i deleted the app anyway. This did not fix the issue though.

Anyone seen this issue before?

I had to reinstall Firefox browser. After reinstalling, I have noticed that the Tracking Protection shield was always grey. For every site I go to, the Tracker Protection summary (dropdown after clicking the shield) always says "No trackers known to Firefox were detected on this page". This is for sites that previously I know Firefox was blocking trackers.

I'm wondering if perhaps during the reinstall I've lost the file of known trackers somehow? Already tried reinstalling and restarting.

Thanks in advance for any help.

At every login screen where Firefox suggests saved logins, old out of date logins are included. I wish Firefox could just offer me 1 last used option. Or at least keep the last used login on top of the list. Now the last used and older logins just appear randomly in a list.

After restarting my MacBook Pro v. 72.0.1 (64-bit) I discovered there was no history or bookmarks and no passwords. No error message on any of these. No new history is being saved. Is there a way to restore all of the missing data?

I'm up to date, using 72.0.2, but the problems described with the article I mentioned are still happening to me. (Tried the workaround fix but it was already set the way I was told to set it, and anyway I'm not on Firefox 70.) Namely and with a specific example, Facebook's top bar loads but I don't get my feed, can't look at my notifications, etc etc. But several other sites have other functionality screwey. I was just ignoring it for a while, because like Facebook is not vital to my life, but now my college's Moodle site isn't working and I can't submit my assignments properly, so I'm going to have to switch browsers if I can't figure out what's wrong. Anybody else still having problems? Anybody have a solution? Thanks guys.

Restore previous session isn't working. I uninstalled and reinstalled Firefox, and it worked again, but as soon as I signed in to my FireFox account, it stopped working. I also disabled all extensions and am still having the problem.

From my public IP of 104.158.49.18 FF ses the web site https://www.publicmobile.ca/ as a potential security risk. FF is reporting this incorrectly as other web browsers show this site as valid. I have included the certificate values.

what is the reason for the error meesage? Someone could be trying to impersonate the site and you should not continue.

Websites prove their identity via certificates. Firefox does not trust www.publicmobile.ca because its certificate issuer is unknown, the certificate is self-signed, or the server is not sending the correct intermediate certificates.

Error code: SEC_ERROR_UNKNOWN_ISSUER

No matter what I have tried I cannot get logins saved. When I try manually I get an error message. A red strip saying "an error has occurred while trying to save this password"

In Safari on the same laptop I can see everything and i can post things. On FF I can see my name en small picture, and how many reactions i have, but the screen stays white, blanco. In the left down corner i can see that FF loads with my name but then nothing happens....I have the latest version installed... YT Jaap Wals jaapwals@gmail.com

I'm cleaning out a bookmark folder and I've noticed that when I deleted a folder or bookmark, it'd come right back as soon as I delete it. I'm using the sync feature so not sure if it's just being over aggressive.

In the Search panel of the Preferences page I have changed my preferred search engine to DuckDuckGo. It will stay as this until I quit and reopen Firefox, when it reverts back to Google. I've tried this a few times but it always goes back. I've looked for a cookie that might be being deleted, but there are none on my machine (that I can see).

I'm running Firefox 72.0.2 on a Mac with Catalina 10.15.2 and also have Firefox apps on an iPhone and iPad.

Can anyone shed any light? Thanks in advance

I haven't been able to delete or add to my bookmarks in years! Despite upgrading my MacBook to the latest ios and updating Firefox to the latest version. I've lived with it until now and just haven't used bookmarks in ages, but I want to start using them again. I can't change any bookmarks, in the menu or the toolbar. None of the bookmark buttons or shortcuts work. How can I fix this?

I had this problem with Safari & Chrome but I was able to fix it. I cannot get rid of "search manager." I have looked into all the items listed that I can find but every time I sign onto Firefox, I'm directed to search manager. I just open a new tab. It is NOT listed as one of the search engines. How can I get rid of it? My home page is a blank page.
