Specs
Ranked in these QuestionsQuestion Ranking
Pros
Pro Overall very useful
It takes all of your tabs (choose between all/all-except-current/current/all-to-right/all-to-left) and turns them into links in a special OneTab tab where you can further manage your tabs by dividing them into groups, removing duplicates and securing them so that they can't be removed unless unsecured.
Pro You can organize links by dragging and dropping them
You can drag and drop links/tabs to reorder them by relevance, or to move them from one list to another.
Pro Non-invasive
The OneTab dashboard only appears the first time you open your browser after quitting, although you can also make it appear through the extension button in the extensions bar. This is less invasive behavior than the Chrome extensions that appear every time you open a new browser tab.
Pro Provides just enough information
OneTab provides just the right amount of meta-info about the tabs you've saved. It groups them by session, and tells you how many tabs are in each session, as well as the date the session was created. Every saved tab includes the bookmarked favicon and page title.
Pro Management & sharing of saved sessions
OneTab makes it very easy to restore, delete, share, lock, rename, and favorite your saved tab sessions. OneTab also makes it easy to share, export and import URLs into your OneTab dashboard as a whole.
Pro Open source
Bitwarden is open source and can therefore easily be reviewed and checked for security. Its Github repository is accessible here.
Pro Free
It is easy to start as the majority of features are on the free version.

When a site has multiple credentials (like I have for some brokers and banks), then the most recently used is automatically populated (if auto-fill is opted). This feature is unique (to my knowledge) and spectacular (especially for sites that log you off frequently and re-logging in is required).

Cons
Con Can get messy
The OneTab tab has everything in a list format with just simple headings describing what you have in this or that list. It isn't comfortable to manage it when you have quite a lot of tabs in there.
Con Slightly confusing UX
It's easy to forget that clicking on the OneTab button in the extensions bar doesn't show you options – it saves your current session by closing all your tabs in the given browser window. That might be slightly annoying if you were trying to access the OneTab dashboard or view OneTab options instead of trying to save your current session in OneTab, but this is only a minor inconvenience given how easy it is to restore your session.
Con Clicking on a tab/link to re-open it automatically deletes it from a session
This is not so much a con as much as it is a heads up for those who use OneTab as a form of transient digital bookmarking (like me!). When you click on a tab/link in any given OneTab session, that will cause it to disappear from the list of tabs in that section. It would be nice if there was an interim period or separate place where the link is still visible/accessible. That or it would be nice to have a version history of past closed tabs/links and sessions.
Con Data loss
When you run ccleaner or CleanMyMac, all OneTab data may vanish.
Con Password generator only uses 8 special characters !@#$%^&*
Whereas a desktop keyboard has 30+ special characters. This greatly reduces the possible passwords that can be generated.
Con Unable to remove duplicates
If you import more than one times, it will store its duplicates and there is no duplicate remover on these apps.
Con Passwords cards can be tricky for newbies
The fields can be difficult to understand for newbies. For example, some login pages can add a field for the password name differently at the same time as the password's field will contain a password. When changing the password, they sometime end corresponding and can give headaches to some users.
Con Cloud-based
You're storing your passwords on servers and you have to trust them.
Con Cannot update data while offline
Requires Internet connection.
Con Saving new credentials isn't as easy as it should be
When registering on a new site, Bitwarden pops up a button to ask if you'd like to save credentials (as most equivalent products do). But the button disappears VERY quickly, so often requires manual entry of passwords
Con Input of new login needs a 'signed-up with e-mail = 'example@wherever.org' functionality
Often sites won't be able to reset your password if the corresponding e-mail used in sign-up is unknown.
Con Lack of communication between instance opened in one session
If you use the client's desktop's app, multiple browsers extensions; they all work almost totally independently. Using more RAM as database is opened each time and asking for login more often. Some other passwords managers use desktop's client to open the database and extensions communicate with it in this case. If there's no desktop's, they'll work as standalone extensions.
Con The autofill sucks
The autofill is tedious - many clicks/taps required to trigger it. It doesn't help that the extension is slow to open.
Con Cannot store images of ID card, etc
Attachments available in premium.
Con Web browser extension doesn't recognise login required
User has to scroll/search for web site login details as it is not found automatically.
