Firefox Support Forum

Hello! I have a serious problem. I lost access to my data because I changed my password, so my data is no longer synchronized. I reinstalled my Windows, and I forgot the old password I had on that Windows. As I reinstalled, I decided to change the password because I didn't remember it, but after that I found out that synchronization doesn't work. Please help me, I had very important bookmarks that were there. Thanks in advance!

初めまして Which topic best describes your question?の 選択肢が英語翻訳コピー出来なかったので 下を選択してます。

サポートセンターに問い合わせたら こちらで問い合わせた方が詳しいという メールが届いたので再度質問になります。

ファイアフォックス内の仕様かもしれませんが Twitter等で画像をPC内の保存してるフォルダーから貼りつける時に、メディアを押すと ファイルのアップロードが開くんですけど その際に、ダウンロードやピクチャーなどの 表示が、 (すべてのサポートされた種類)に 初めから固定されています。 (すべてのファイル)に変えてからじゃないと 表示されない画像などもあって すべてのサポートされた種類から すべてのファイルに変更しないといけない手間が かかってます。

直接PCからのエクスプローラを開いたら 全てのファイルにも出来ますが ファイアからなのか他のブラウザかTwitterでの 仕様なのかは調べてないですが もしファイアフォックス内で変更が 可能であれば教えて頂きたいです。 質問前にAIチャットで質疑応答してますが ファイアフォックス内の設定にダウンロードする際にすべてのファイルを選択肢があれば可能なども 言われましたが、そのような項目は見つからなかったです。後は、PC本体の設定から規定のアプリでのファイアフォックスのファイルの種類または規定リンクの種類を変えることも提案されましたが htmやavgfなどコード変えたりの そこまでの知識もなく弄るとPC自体おかしくなったら嫌なので出来ませんでした。

長くなりましたがよろしくお願いします。

Hey

I completely reseted my pc a month ago or something like that and i had a bunch of tabs that i synchronized. Today i wanted to open one of those but i couldn’t find it since they are all in the inactive folder. The thing now is i can‘t get em back anymore because the sync folder was from the reseted profile. is there a possibility to get everything back?

Hi,

Yesterday I set up a new computer, installed Firefox and logged in to my Firefox account. Everything went well, my bookmarks appears, all (!) my extensions were installed, everything looked fine. Then I went about my way configuring unrelated Linux stuff, using Firefox as normal on both computers, no problems.

But at some point, I suddenly noticed that on both computers, the icons for most of my extensions had disappeared. And sure enough, looking in about:addons, all that was left were five addons (Dark Reader, Simple Translate, uBlock Origin, Dictionary Anywhere, OneTab). And on both computers, including my main laptop (!), where I hadn't done anything other than clicking around in websites.

And it only affected the extensions, my bookmarks, history, etc all is fine and synced between the computers.

No restarting of Firefox, choosing different profiles in about:profiles (there was only one other, a mostly empty one), nothing got them back. And looking in ~/.mozilla/firefox/, sure enough extensions.json and all extension related folders had been changed, looking as if I never had more than these five extensions installed.

And when I installed one of my usual extensions again, all of it's settings and customizations were back to default. So this is not just a case of having to reinstall a few extensions. All custom uBlock filters, all Tampermonkey scripts, etc, everything is gone.

I tried looking around on the web for solutions, but it appears that there is no one who has had this exact issue before, and I couldn't find any indication that there is any way to revert such an error by Firefox Sync.

To my luck, I have a secondary laptop where I should have a mostly up-to-date instance of my Firefox profile, from which I will now try to recover my extension data, but if that weren't the case, years of fine-tuned settings and customizations would be gone.

As people rely on Firefox Sync to back up their Firefox data, instead of backing up their Firefox data "against" Firefox Sync failing like this, I'd think this is not something that ever should be possible to happen. At the very least, there should be some way to revert errors like this. Perhaps Firefox Sync could store backups either server side or client side before syncing deletions like this?
