works great but why does it need permission to access all my data from all websites? Disabled.

Esta mas o menos bien

Leider kein Dark Mode, da bekommt man ja Augen-Infarkt beim Umschalten.

Je ne trouve pas comment régler l'extension sur firefox (en cliquant droit sur le logo de l'extension) alors que c'est possible sur chrome. Arrangez ça svp.
Sinon pour régler les options il suffit de cliquer sur le bouton de l'extension et une page s'ouvrira...

I suspect this is slowing down my start-up time but I have no way to check how

Usability wise and task wise: it is to the point and does exactly what you want it to do.
Accessibility wise tho? Not so much. The only thing that would make me bump it up to a 4 or even 5 star review would be if the tabs could be synced to other devices or to your Firefox account you use to sync tabs and the such. There have been many cases where I had to clear cache because something was acting up or my cache was just bogging up space and lost my tabs as a result of said clear.

TL;DR Crashes Firefox = lost tabs -
Using Firefox on Windows 7, the intended feature works well however, it causes Firefox to crash every 1-4 hours. It does not crash on execution, nor depending on the number of tabs open. This bug would be alright if Firefox would then load the previous windows/tabs like it usually does upon reopening... but something about the crash causes the last window you were focused on to be deleted from memory. It doesn't load on reopening (other windows will) and "history" rarelyy has record of it. (Sometimes you can just go history -> closed windows and reopen but typically there are no "closed windows" listed in that list.) I'd give this a lower rating if other "session manager" add-ons were available for Firefox the way they are available for Chrome.

Works as intended with one very annoying "feature", whenever you open your browser the one tab page auto loads after a delay of few seconds and steals the focus from whichever tab you were previously on. So if you open your browser to quickly go to website or to google something quick, while you are typing in the address bar suddenly you get switched to the One Tab page. I would prefer if there was a option in the settings to disable this so that you can open the one tab page only when you want.

It's OK. as long as all of the tabs are loaded in Firefox (not asleep), this extension will suspend them to the mobile browser; for this I'd recommend a feature that refreshes all Firefox mobile tabs, if that is possible. My one biggest gripe is that it is lacking many features from the desktop version, such as the option to not open onetab at startup. Please add these, as it is really annoyong having the onetab page pop up whenever I open a link in Firefox.

firefox android. приходится несколько кликов делать. 1.открывается окно onetab. 2 нажимаем отправить все вкладки в onetab. лишнее действие, имхо.
и отправит не все. только часть активных, может вообще 1 вкладку из сотни. зато закроет все вкладки.

Neat app. But couple of issues.
* No Darkmode, despite my firefox using dark theme. No option in app for choosing it.
* Sync ability with firefox account or any cloud option.

it would be so much better if it was like the chrome

I used to have this Addon on the Chrome Browser. Now I tested it yesterday on Firefox. The only feature that this addon is lacking, is the <> to find Tabs Quickly. And the ability to separate Tabs into several Groups. For Example: YouTube Group (with all the video tabs), Design Group (tabs for design websites), etc...
Because I have more than 1000 tabs open So I can not find easily what I want. I will update my review when They add these two important features.

One-tab doesn't work in newest Firefox Dev for Linux,
it's only showed white screen.
Please fix it. I use it every day.

1-17-25 not saying much but one of the better ffox addons. still waiting for them to add and easy save feature that does not delete sites after deleting browser cache.
12-21-24: pretty good. needed a easier way to make tabs permanent, not subject to deletion on simple cache delete. easier way to search and save important tabs needed. sometimes screws up and you have to reload it. slow to call up. better way to find dupes and delete them.

but not always. a little too slow. Still no better easier way to save onetab files, import and export-still cutting and pasting to do it. Need an easy way to sync across several browsers. useful extension, better than using bookmarks.
5-2-23: Slow as hell. autoway to save tabs to backup file. Sometimes requires restart to get it to display the tabs. Another example of an addon with great potential that needs a developer that can deliver. Need to add auto save to addon.
11-25-22: what can you say about an addon that has such promise but comes up short. Does not work on epic browser-requires constant enable with each use to get the list. VER.Y SLOW in putting up the list on multiple browsers including ffox. makes your links into "SHARES" instead of just saving them like you asked. then you have to delete the share and make a new list again. buggy. inconsistent button implementation. No feature to saving your list, you have to do it manually. No user guide worth mentioning. Just another "recommended" clunky rather junky addon. better that bookmarks, but that's not saying much.
10-2-22 does not load with epic browser, won't work properly on most browsers, slow or unable to load it, requires disabling and re-enabling. Cannot save your links to plain text, cannot backup your links, another script kiddie addon from people who really cannot program.
9-2-22: THE MOST annoying thing about this "recommended" pos is that you constantly have to deactivate it and then reactivate it to get the dam POS to load the entries. A royal PITA to use it. Takes forever to load the entries and sometimes autodeletes them even when you set it to lock them. Like most of the "recommended" addons here, just goest to show how meaningless Mozilla's "recommendations" are. Lacks proper instruction and notice on how to adjust it's settings. Why can't "developers" write programs that JUST WORK???
8-1-22: The developers of this app are either lazy or not very competent. They hardly ever fix bugs, like your needing to deactivate and reactivate one tab to get it to show the saved tabs. No way to autosave your tab page. cannot set tabs to autolock so you have to do it manually each time. Another "recommended" addon that never quite works well.
6-25-22: Buggy. Won't load in many cases you have to disable and reenable it to get it to load and it's SLOW in loading. Should be able to "LOCK" site urls with a universal setting, now you have to do it individually. Slow to load, slow to work, the keyword is SLOWWWWW. Probably spyware, aren't they all? Save your urls manually has no way to do that from withing program. If the program loses them you are uked.
12-11-21 updates: auto opens second window without user input. cannot connect to tor as a result. Lost many tabs saved for no apparent reason. recommend you manually backup any important tabs. Have to disable it frequently to use tor or to prevent problems with it opening a second browser window w/out input. Needs work.

Works well on desktop. Does not work on mobile -- it closes tabs without saving them.

Ok, at first I wrote a negative review but on a second try it seems to be working fine, once I got the hang of it.

Will add more after some use. On another droid I often wind up with 50-60 tabs open, which gets kinda slow and uses lots of memory, so this will be really handy there.

cheers

I *highly* recommend this add-on. However, since a recent Firefox update it has crashing my browser when I click the OneTab button.

This is with Firefox 68.0.1 on Linux.

Please help me I lost all my tabs but I found the file storage.json.migrated which contains all my tab data. I can't use this to import it into OneTab

Why is this permission required?
"Access your data for all websites"

The Firefox docs mention that: "The extension can read the content of any web page you visit as well as data you enter into those web pages, such as usernames and passwords."

This addon's extremely useful to me but I find the use of that permission unnerving.
